  1. 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.

    Planet 51 pays homage to the classic alien movies in which it references much from movies such as Aliens and 2001: A Space Odyssey, in which they are really fun and they keep an adult's attention. Personally, my list of favorite animated movies includes peculiar titles and not the usual classics, Planet 51 fits there perfectly. Full Review »
