I disagree somewhat. True, environmentalism isn't the main goal of the film, but it's clearly implied several times that he wants to destroy the theater for oil profits. Even if they had kept his childhood plotline in tact, the fact that he's an oil baron wouldn't suddenly become irrelevant to his motivations. Again, it's surprising to me that we're all responding to Fox News by saying, "Oh no, no, there's no liberal message at all!" Why are we trying so hard to back away from that?
