Just got back from seeing it. It was a very beautiful film in every possible way. The only slight negative I have is that all the running around on the spaceship got me slightly a little bored but I was still in awe the entire time.
And really, I didn't see the film as being "stop buying stuff." I saw it more of technology becoming too advanced so that it does everything for us. Other than the advertisements, I didn't see anything that screamed "we are overconsumers!" Nobody even bought anything from what I remember. It was just technology is doing everything for us, that's becoming the norm. They didn't buy all that technology, everybody alive lived there -- it's their way of life now.
And, I interrepted that last scene, that it took a while for all the memories to register for Wall-E. Like, they were all there, but the touch is the one thing that activated it. Sort of like Dory, when she saw the address and it all came rushing back to her. Something like that.
But MAN -- that last scene was dramatic. I happened to go to a showing that was almost all kids, and they were yelling/laughing/screaming throughout the whole film (but not enough to distract from it), but there was complete total, dead silence when EVE held his hand at the end. If somebody even so much coughed I would have jumped a mile!
I really did love this film, Pixar is so good at creating an atmosphere/mood. I really can't imagine anything that could be done to improve upon this film, it defines the word masterpiece. Dare I say it... I may have even shed a tear or two. It's in the Top 5 of IMDB's Top 250 (but will go down in due time).
