    The worse animated film I've seen in quite a while. 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.

    Its not the best animation movie of the year, but its really funny to see, with high quality 3D, simple argument (But simple isn't bad) with some memorable jokes. Ill be really proud if my first animation movie would be like that!! I recommend it. Full Review »
