Planet 51 is the animated tale of man's arrival on an alien planet, which showed no signs of intelligent life, but they were wrong, very wrong. The world is not only inhabited, the entire culture is that of 1950s America - if only everything hovered back then. After planting the flag in someone's backyard U.S. astronaut Captain Charles T. Baker discovers he's not alone and promptly goes into hiding, pursued by the planets military forces and a mad scientist.
The entire movie is played strictly for laughs, but the humour is quite forced. To keep the nerds happy there are hundreds of other movie references to spot. I knew what to expect but was still disappointed, if you liked 'Monsters Vs Aliens', then you will equally enjoy this movie.
