The best way that I find to describe this movie is FUN!!! OK, so it's not an earth shattering/world changing movie, but by Golly, it's FUN! I highly recommended... you'll feel good coming out of the theater... just be warned, Pierce Brosnan voice.... ouch!
Aside from being a really nicely animated movie, Wall-E carries a great message that hopefully adults will be able to understand and explain it to their children (as well as themselves!). Pixar does a great job humanizing the main character(s) and exposing the grim image of what Earth could become (in large excess, of course!) if people's attitudes don't change and we do something about it now. I give it two thumbs up!
