There have been countless animated movies that have fallen flat (Doogal, Space Chimps, Shrek the Third, etc.) and some that have triumphed (Up, Surf's Up!, The Incredibles, and so on). Planet 51, an animated family comedy from inde production groups, probably falls in the middle. To start with, the character animations, particularly the astronaut's, is superb. But the backrounds are heinous and distasteful. When you have a few good animated characteristics and some bad ones, the movie won't end up looking too good overall, and that's basically what happened here. The jokes are low-brow (to say the least) and some are really offensive. They involve naked humans, anal probes, and "hooking up" references, so this is best reserved for younger tweens and up. Older viewers will appreciate references to 50s' music and movies, but there is simply too much product placement to ignore. All in all, Planet 51 is a decent animated comedy that falls flat in trying to be new and age-appropriate, but may intice viewers with its homage to 50s' products and people. Still, it has far too many vulgar talk to be completely family-friendly.
