    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.

    Although not bowling me over, Planet 51 is a jolly and good-looking animated feature in glorious 2-D.
  3. A perky though not terribly imaginative feature aimed primarily at youngsters.

    What's missing is originality and story and inventiveness.
  5. 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.

    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.
  7. Bursting with potential that never gets realized.
  8. This movie, which was made by an animation studio in Spain, isn't trying to make a social statement; it speaks in the international language of lightweight comedy.

    It's a missed opportunity. The premise is OK enough, even if it is like one of those old "Star Trek" episodes.

    Largely, it’s a jellybean of a movie: bright, colorful, sugary, and with no real content.
  11. Movie references abound, but there's not enough humor to fuel even 90 minutes.

    Perhaps Planet 51 should have added a dash of Pedro Almodovar, one of Spain's preeminent directors.

    Neither the film’s main players nor its random period spoofery has any personality.

    Like "E.T." in reverse, this pleasantly mediocre CG animation tale lands an astronaut on a distant planet.
  15. Agreeable but flagrantly unoriginal.

    There's nothing funny, provocative or involving about what "Shrek" co-writer Joe Stillman and the team from Madrid-based Ilion Animation Studios do with the notion here.

    The script lacks wit, and the in-joke references to cinematic sci-fi classics will soar over little kids' heads without pleasing many adults.
  18. Planet 51 is cute, but it's no "Shrek."

    Young children and adults with high pain thresholds will enjoy the movie during its brief pause on the way to your On Demand menu.

    Yet the moral at the end is that we should all be more tolerant of different cultures. Is that really true, though, if the culture you're trying to tolerate is trying to open your skull with a circular saw?

    While expertly executed animation-wise and passably entertaining for very young kids (less so, their parents), is still as dull as the hull on Rocketship X-M.

SO predictable! NOT funny. The movie could not hold the attention of most of the kids in the theater as they were noisy and fidgety. By comparison, when I saw Wall-e in the theater you could hear a pin drop. I'm giving it a 2 because the animation is descent and there is one funny line when the aliens see the human naked. Otherwise it's a ZERO. AVOID this bore-fest! Full Review »

    PLANET 51 is a nice, little kiddie film that has many great homages to famous sci-fi movies.
