Just saw the movie, so finally commenting. I assume *spoiler alert* is redundant at this point. 
Going back to the page 2 discussion about the fuel and transformation, and why it took 20 years for them to get it; I'd say all that stuff is in there to lay the groundwork for the sequel, so its intentionally unanswered in this film. The scene where the 3 Prawns were scavenging for that stuff seemed to hold some clues though. "That's human technology, it's useless" Which indicates it took them 20 years to find pieces of THEIR technology with which to extract enough fuel. Which then begs the question (or at least in my mind) - was some of their technology already on this planet before the ship arrived then? I have some wacky theories about that, so hopefully a sequel gets made to see if I'm even close.
@ryan I kind of felt the same way towards Wikus, so I think I know what you mean. All of his actions are basically just to save himself, but hey, maybe that's just who this guy is. However, isn't that more believable for a character who'd basically been herding these aliens for 20 years, (and was not too upset when they got shot in front of him as he's trying to relocate them), rather than if within 1 hour of the movie he suddenly became a Prawn-rights avenger?
If you are looking for a moment of redemption for him, what about when he came back to rescue Chris though? By that point, he'd already been told he couldn't be changed back for 3 years, but when his mech heard that they were going to kill Chris he came back to save him. So he did put his life on the line there with nothing to gain. More than I've ever done for another human, let alone a crustacean.
I am obsolete. This must be what old people feel like. And Blockbuster.
