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

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

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.
