Just finished it up. Solid flick. Not perfect, but what is? The reported hammering home of the message was more of a nudge. It's no worse than any of a million other movies with a message. The current social climate requires you to pick a side and pretty much be damned whatever you do because you'll still be wrong. I think it used a familiar modern parlance and held a mirror to current events that might have struck a chord with many.
My biggest issue was Foster. She probably could've been removed entirely and the movie would be better. There was plenty of good guy bad guy with Damon and Copley and I saw a cleaner way to get from point A to B with no Foster.
All in all if you liked District 9 you should enjoy this. Excellent effects and weaponry are also on display. I feel they are equal but like many would have liked to see it surpass it. Maybe next time Neill can slow it down a bit. I was really surprised by Copley. He appears to have a good range in his work and there wasn't enough of him here. I can't say much about Damon. He stuck out like a sore thumb for obvious reasons. As a scifi/fantasy fan this can stay on the keeper pile.Warning: Spoiler! (Click to show)
As for removing Foster, I'd do the story similar to this:
Microwaved Damon seeks Spider to get to Elysium, hit goes out on suit BUT Damon and Spider make him write that code, suit in distress gets Kruger called in to save suit (previously fired for shooting down civilians), Kruger is like I CAN USE THIS TO GET ELYSIUM, Damon is like OH HELL NO, fight, Damon escapes, Kruger chases, Damon goes to see Dr., etc, etc...No Foster more crazy arse Kruger
Also might ditch Damon for a more appropriately flavored actor
