This movie lives up to its hype. The actors are all stellar, and this movie is the best superhero movie ever! However, it is quite dark and definitely NOT for young children. That PG-13 rating is spot on. I know everyone keeps saying Heath Ledger, Heath Ledger, Heath Ledger, and he is fantastic, but every actor in the movie provides a stellar performance. Go see it then see it again!
This is definitely an uncomfortable movie for Americans to watch, as it pokes at a future where a conglomerate runs the population, humans ruined the planet with trash, and people are completely sedentary and never socialize in person, even though they are within inches of each other, because they are too "plugged in" to the network. And these are only SOME of the social comments in this movie. If you can look beyond the social slams, the movie is pretty darn amazing from the animation to the story of Wall-E and Eve. This movie is definitely another home run for Pixar and worth watching.
