This was ONE of my problems with the movie. In the beginning they showed that it took little effort to cut through the doors/hull of the ship, but 28 years later there was no visible change? You mean to tell me there wouldn't be a massive effort to salvage as much alien tech and materials from the ship as possible over the course of nearly 3 decades? The only evidence that we're given that humans have any interest in the ship itself were the long shots that used helicopters to provide a sense of scale. There should have been non-stop crews ferrying materials down from that thing 24 hours a day. It should have been crawling with research teams, anchored to the ground, etc. I realize that the movie was about the Wikus, but I think the storytellers dropped the ball with what was happening in the background. My opinion...

Michael Moore should do a documentary about the DeBeers cartel. Although, I'm not sure how he'd tie THAT back into Flint, Michigan. You don't think a sweaty doughy white-guy would stand out at all hanging out around an African diamond mine, do you?
