How does Pixar do it?? They get away with absolutely ripping apart the cruise/entertainment industry, mega-monolith companies, and our own slovenly nature - in such a way that is too true for Disney or anyone else to say it goes over the line. They say things that many of the rest of us are too frightened to say about society. Much like the theme in the Incredibles, where they actually say that we aren't ALL special, these are ideas that I am happily surprised to see addressed.
The love story was perfection. The contrasts in technology, fantastic. The ruined earth in the beginning touched me to my very root of guilt and concern.
One thing that I found interesting was that immediately after the movie, GD mentioned Wal-Mart, and I realized that even as I cringed every time BnL's logo came up, it wasn't pushing that particular trigger. I was thinking of media/entertainment conglomerates. The point of BnL to me is that it doesn't matter where it started, because it was everything. It seems that I'm more afraid of them than I am of Wal-Mart. Oh, and Best Buy came to mind as well.
The over-sweet, rather unlikely happy ending was the only flaw I saw - but there was no other way for them to play it. How could the humans just "wake up" by bumping into Wall-E and suddenly want to start working for a living? Yeah, they were stuck.
I keep thinking of all the imagery, and I don't think it'll leave me any time soon. Awesome film.
Oh yeah, and the Main Street song!
