Name : Leah Greenblatt / Alias : Entertainment Weekly
As silly and sometimes nonsensical as it is, the movie is surprisingly sweet and well-intentioned.

Name : Ben Sachs / Alias : Chicago Reader
Jon M. Chu, who directed the concert doc Justin Bieber: Never Say Never, maintains a lively pace, and there's some cute business involving a robot that communicates through music.

Name : Neil Genzlinger / Alias : New York Times
It seems to be merely tossing ideas into the pot that it thinks might appeal to 9-year-olds.

Name : Patrick Dunn / Alias : Detroit News
Hardcore fans won't find much of the Jem they loved under the movie's achingly hip millennial trappings, while young newcomers will be left wondering what a robot has to do with a rock band.

Name : Ignatiy Vishnevetsky / Alias : AV Club
Its one saving grace is that Chu's direction is so wildly inconsistent that it manages to produce a handful of genuinely gorgeous images alongside all of the cruddy ones.

Name : Sara Stewart / Alias : New York Post
Director Jon Chu stretches "Jem" to a ridiculous 2 hours, via endless amateur-musician YouTube clips. Anyone can be a star, they attest - and always be yourself! (Except when you're Jem. I guess.)

Name : Rebecca Keegan / Alias : Los Angeles Times
In revisiting the pop rock quest of a multiracial group of adopted sisters in suburban California, Chu has made a stylish and self-aware musical fantasy for the YouTube generation.

Name : Molly Lambert / Alias : Grantland
What it lacks in humor it makes up for in sheer weirdness - it's a master class in How Did This Get Made? It feels focus-grouped to within an inch of its life, but it's so strange that it's impossible to imagine what process led us here.

Name : Linda Barnard / Alias : Toronto Star
Jem has lost her outrageousness and gained a robotic sidekick in an overlong, low-budget big-screen reboot of the 1980s toy-selling cartoon series.

Name : Geoff Berkshire / Alias : Variety
The film seems inexplicably embarrassed by its roots, instead serving up half-baked and self-consciously contemporary drama that no one in the sure-to-be minimal theatrical audience will remember quite so fondly some 30 years on.

Name : Scott Tobias / Alias : NPR
Jem and the Holograms is Mac and Me to Josie and the Pussycats' E.T.

Name : Alan Scherstuhl / Alias : Village Voice
The movie's poky and confused, never clearly setting up its conflicts and blowing far too much of its running time on a National Treasure clue-hunt for messages Jem's father programmed into a sassy dancing robot.

Name : Jim Slotek / Alias : Toronto Sun
After a few crackling, resonant digital-age scenes in the opening act, the filmmakers settle in and make Jem into a mediocre Disney Channel movie - with, for no good reason, a pet robot.

Name : Alonso Duralde / Alias : TheWrap
Even though I wish the songs themselves were stronger, there's an energy and a vibrancy to the movie that its young target audience will appreciate.

Name : Julia Cooper / Alias : Globe and Mail
There's hardly tension, barely any drama and the sugar high you might expect from an eighties redux is replaced by a dull aspartame buzz.

Name : Frank Scheck / Alias : Hollywood Reporter
Not being part of the generation that watched the show, I can't vouch for its merits. But it's safe to say that it must be miles ahead of this wan, bloated screen version which forgoes the original's sci-fi and thriller aspects.

Name : Richard Roeper / Alias : Chicago Sun-Times
Schumer's performance is a tour de force of razor-sharp comedic timing.

Name : Liam Lacey / Alias : Globe and Mail
There's a funny movie in Trainwreck, but you may have to sift through a lot of debris to find it.

Name : Joe Williams / Alias : St. Louis Post-Dispatch
This is a fully fleshed-out movie, the funniest of the year.

Name : Preston Jones / Alias : Fort Worth Star-Telegram/DFW.com
Trainwreck is a tart blend of frank sexuality and domestic drama, giving audiences something they rarely see at the movies: a woman unapologetic about wanting sex.

Name : Sara Stewart / Alias : New York Post
"Trainwreck" is a corrective to a lot of outdated cliches. It's very funny and sweet and even a little weepy, and it has maybe the best scene ever filmed of dirty talk gone wrong.

Name : Tom Long / Alias : Detroit News
The absolute best thing about this film, aside from Schumer's strong, smart voice, is the promise of more to come. This lady's just getting started.

Name : Alonso Duralde / Alias : TheWrap
Ultimately comes down in favor of mainstream girl-gets-boy in a way that Inside Amy Schumer might find a little dubious, but it never feels like Schumer is aggressively watering down her uniquely prickly brand of comedy for a mass audience.

Name : Lindsey Bahr / Alias : Associated Press
If you're looking for something radical, you'd be best to stick with Schumer's television show. Trainwreck is just good fun, and a lot of it at that.

Name : Moira MacDonald / Alias : Seattle Times
There's nothing remotely fresh about this plotline (or the way Apatow, true to form, makes the movie 20 minutes longer than it should be), but "Trainwreck" works as comedy more often than it doesn't - and that's rare enough.

Name : Andrew O'Hehir / Alias : Salon.com
"Trainwreck" is not very good, but Schumer is frequently amazing in it. Officially, her fans will not be disappointed; not far below the surface, it's a bummer.

Name : Chris Nashawaty / Alias : Entertainment Weekly
Beneath all of his bad-boy shtick, Apatow's always been a pretty conventional moralist. But Schumer gives their raunchy rom-com enough of her signature spikiness to prevent it from ever feeling predictable.

Name : Cath Clarke / Alias : Time Out
You forget how limited so many movies' ideas of women are until Schumer launches into an extended tampon joke. It's a film about everyday sexism and double standards.

Name : Scott Foundas / Alias : Variety
Amy Schumer and Judd Apatow craft a winning portrait of a good time Sally in the grip of her first serious relationship.

Name : Joe Morgenstern / Alias : Wall Street Journal
The movie veers sharply off track toward the end. Still, the sum of its most memorable parts is great fun.

Name : Mick LaSalle / Alias : San Francisco Chronicle
Romantic comedies can go in all sorts of directions, but they depend on the audience's believing that a couple should get together and stay together. But in "Trainwreck," that belief is hard to come by.

Name : John DeFore / Alias : Hollywood Reporter
Schumer has never had anything like a leading film role, but self-revealing stand-up and a TV series have limbered her up for the job.

Name : Christopher Orr / Alias : The Atlantic
This is a film that belongs not to its director but to its star, who, if there is any justice in the world, is about to ascend from cult icon to mass phenomenon.

Name : Jesse Hassenger / Alias : AV Club
Unlike many comic vehicles and just as many big-city romances, it's a real, and ultimately rewarding, piece of work.

Name : James Berardinelli / Alias : ReelViews
Trainwreck is brash, funny, and often vulgar.

Name : Ty Burr / Alias : Boston Globe
"Trainwreck" serves as confirmation that a star is born, a seemingly average woman whose above-average superpowers include reminding us of our own. Where she goes from here should be fascinating to watch.

Name : Esther Breger / Alias : The New Republic
People who go into Trainwreck looking for that Amy -the subversive truth-teller, the feminist role model - are likely to be disappointed. Their loss. Trainwreck is a surprisingly old-fashioned romantic comedy, the kind that rarely gets made anymore.

Name : Bill Goodykoontz / Alias : Arizona Republic
Once the romance takes off, the entire film shifts. It becomes more of a conventional romantic comedy, albeit one with really dirty words. And it remains hilarious, because Schumer seems to be incapable of being anything else.

Name : Anthony Lane / Alias : New Yorker
So much for the promise of the title. "Trainwreck" sticks to the rails.

Name : Michael Phillips / Alias : Chicago Tribune
Schumer and Hader are wonderful together. Gender inequity in the world of comedy deserves all the overdue attention it's getting, and more. But there are matters of craft, wit (no matter how crude the jokes) and timing that transcend chromosomes.

Name : Brian Truitt / Alias : USA Today
With films such as Funny People and This Is 40, Apatow has toyed with finding the right blend of the serious and the hilarious and finally hits it here.

Name : Christy Lemire / Alias : RogerEbert.com
It's a familiar rom-com dynamic, but the reversal of traditional on-screen gender roles-combined with Schumer and Hader's easy chemistry-makes "Trainwreck" feel new and fresh.

Name : Stephen Whitty / Alias : Newark Star-Ledger
Schumer's pretty wonderful, and the movie - in a summer that was still waiting for its R-rated smash - is great fun.

Name : Colin Covert / Alias : Minneapolis Star Tribune
While I can't say I felt love at first sight for "Trainwreck," it is a raw and honest romantic farce, even when it is upside-down wrong.

Name : Rafer Guzman / Alias : Newsday
Despite Schumer's subversive instincts, the romantic comedy remains unchanged.

Name : Bruce Demara / Alias : Toronto Star
A film that crackles with edgy and boundary-pushing wit.

Name : Ann Hornaday / Alias : Washington Post
What makes "Trainwreck" work is that [Schumer] approaches every beat - funny, serious and in-between - in an open, undefended state. And she's blessed with the perfect opposite number in Hader .

Name : Jacob Hall / Alias : New York Daily News
Schumer raises Apatow's game beautifully. Her biting, pitch-black wit and his penchant for character-driven comedy go together like gin and tonic.

Name : Lisa Schwarzbaum / Alias : TIME Magazine
In the way of most Apatow films, Trainwreck is a little too long, a little too shaggy and a little too conservative in insisting that all's square in love and war.

Name : Stephanie Zacharek / Alias : Village Voice
Apatow and Schumer probably believe they've made a feminist picture, but the reality is something different. This is a conventional movie dressed as a progressive one.

Name : Dana Stevens / Alias : Slate
[Schumer] takes the romantic-comedy heroine and the onscreen treatment of feminism to places they've seldom, if ever, been before.

Name : Steven Rea / Alias : Philadelphia Inquirer
Trainwreck is anything but.

Name : Linda Holmes / Alias : NPR
Trainwreck . has some very traditional romantic comedy elements, including a big, implausible finish. But even if you know where you're going to wind up, it takes interesting side trips along the way.

Name : Rebecca Keegan / Alias : Los Angeles Times
A surprisingly touching and raucously funny R-rated comedy written by and starring Amy Schumer.

Name : Peter Travers / Alias : Rolling Stone
Sweet is not how Schumer wants Trainwreck to go down. She wants to explode rom-com cliches and replace them with something fierce and ready to rumble. Done.

Name : Chris Vognar / Alias : Dallas Morning News
Apatow and Schumer know that sturdy comedy benefits from the stuff of real life, and they supply it in consistent and sneaky fashion.

Name : Wesley Morris / Alias : Grantland
It's got no rhythm or reliable comfort zone. The jokes and ensemble scenes are all rushed, so you can't savor them or what anyone in them is doing.

Name : Manohla Dargis / Alias : New York Times
Often extremely funny, even if it never approaches the radicalness of [Schumer's] greatest, most dangerous work.
