  1. A perky though not terribly imaginative feature aimed primarily at youngsters.
  2. 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.

    What's missing is originality and story and inventiveness.

    Largely, it’s a jellybean of a movie: bright, colorful, sugary, and with no real content.
  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.

    It's a missed opportunity. The premise is OK enough, even if it is like one of those old "Star Trek" episodes.
  8. Bursting with potential that never gets realized.

    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.

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

    The script lacks wit, and the in-joke references to cinematic sci-fi classics will soar over little kids' heads without pleasing many adults.
  12. Agreeable but flagrantly unoriginal.
  13. 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.

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.
