I love DCA and I know there are some of you that say that "they" failed in their execution of the plan, but I still love it.
I love DCA as well. When it first opened people seemed to dislike it. While theres many things I would have done different its a fun park I enjoy. I tend to spend more time at DCA than DL.
Of course it was greed, albeit coupled with the dreams of all who came.
I don't know why you felt that the movie made people and corporations look greedy. I didn't get that out of the movie. I didn't walk out of the movie thinking about greed. I walked out of there touched and thinking about what a great country we live in, how awesome we are as a people, and how we are given a chance at a great life and it's up to us to choose what to make of our opportunities. I walked out of there hoping that my son understood that the opportunities our predecessors had to fight for should not be squandered, but instead celebrated and utilized. I only pointed out that people moving West and taking other peoples' land could be construed as greedy because you mentioned that you and people you went with all thought it made people and corporations look geedy and evil. If that's how you saw it, then that's how you saw it I guess. 
He likes Bugs Life/It's tough to Be a Bug. I could take it or leave it. I don't even find it all that funny. Different strokes and all that stuff makes the world go round...
