"Escape from Planet Earth". Meh. Kinda lame.
I imagine even kids would find this movie kind of boring.
Yes, it has some funny bits. But its not overly exciting, the plot is James Bond-esque (evil villain planning to destroy all the planets), and the sibling rivalry between the two main characters is more childish than realistic.
But to be fair it is a film for children - except I think it fails even as a children's film.
All the best parts are in the movie trailer. So watch the trailer and skip the movie.
