Roger Moore, Orlando Sentinel: Read more
A.O. Scott, At the Movies: The whole thing is just terrible. Read more
Kathleen Murphy, MSN Movies: Rest assured that nothing of significance will disturb said infant, neither feelings nor images nor ideas. No danger here; just a faint, faraway tickle of boredom. Read more
Stephen Holden, New York Times: The agreeable but flagrantly unoriginal Planet 51 belongs to the mix-and-match school of animated moviemaking. Read more
Tasha Robinson, AV Club: Largely, it's a jellybean of a movie: bright, colorful, sugary, and with no real content. Read more
Ty Burr, Boston Globe: Young children and adults with high pain thresholds will enjoy the movie during its brief pause on the way to your On Demand menu. Read more
Cliff Doerksen, Chicago Reader: The script lacks wit, and the in-joke references to cinematic sci-fi classics will soar over little kids' heads without pleasing many adults. Read more
Amy Biancolli, Houston Chronicle: The movie as a whole isn't exactly ground-breaking, and some of the humor tanks. But it has enough action, laughs and candy-hued visuals to satisfy the target audience without plunging grown-ups into despair. Read more
Nancy Churnin, Dallas Morning News: Definitely a planet worth a visit. Read more
Tom Long, Detroit News: Mediocre, clunky and just so not special. Read more
Adam Markovitz, Entertainment Weekly: Delivers a few pleasant surprises, including a smart story -- a reverse-E.T. riff that plops an American astronaut down in a world of just-like-us-only-green creatures -- and clever characters... Read more
Glenn Whipp, Los Angeles Times: Instead of spinning its spoof of 1950s sci-fi paranoia in new directions, the movie trades in potty humor and tired sendups of The Terminator and Star Wars. Read more
Joe Neumaier, New York Daily News: This sharp-looking but unimaginative adventure hasn't the wit of similar kiddie flicks. Read more
Kyle Smith, New York Post: "Singin' in the Rain" references? John Glenn? Cold War duck-and-cover drills? What time capsule yielded this script? Read more
Gary Thompson, Philadelphia Inquirer: An uninspired computer-animated feature that may satisfy undiscriminating pipsqueaks and nearly no one else, Planet 51 is a low-IQ E.T. in reverse... Read more
Roger Ebert, Chicago Sun-Times: Although not bowling me over, Planet 51 is a jolly and good-looking animated feature in glorious 2-D. Read more
Rick Groen, Globe and Mail: With nowhere to go except toward that incongruous moral, the story is getting thin on the ground, obliging director Jorge Blanco to pad with the usual plush stuffing -- bland action and busy edits. Read more
Derek Adams, Time Out: There's enough of a storyline here to keep younger space cadets moderately settled. Read more
Claudia Puig, USA Today: This has the directionless, recycled feel of a script by committee. Read more
Todd McCarthy, Variety: A high concept gets low execution in Planet 51, a lame-brained toon that even kids will recognize as an insipid goof on sci-fi conventions. Read more
Brian Miller, Village Voice: Planet 51 mainly succeeds at reminding you of all the better movies that inspired it. Read more
Michael O'Sullivan, Washington Post: Planet 51 is cute, but it's no Shrek. Read more
