I saw Elysium two weeks ago on Sunday in IMAX.
Really enjoyed it, had an interesting comparison to a few current issues and it was 'similar' to District 9. Had some shooting, some weird weapons, and had a number of people get gibbed brutally like the director played Doom before writing it.
Sadly it wasn't as memorable as District 9 but still a solid movie. Still had the annoying shaky-cam for the fist fight scenes, less than there were in District 9 but still enough to make me not really understand who was winning during the various brawls.
Copley's portrayal of an insane mercenary stole the show away from Matt Damon, hearing him speak menacingly in a South African accent was both comical and horrifying.
It has exoskeletons, a Halo-esq ring place, some goofy remote detonating homing shuriken things, a guy getting his face blown off then repaired via a magical med bay, and at least two people blowing up Fallout bloody mess style (Arms and legs shoot off like rockets)
Hope it makes enough money to finance District 9 sequel and maybe get Copley some more work, preferably more of him as Murdock from the A-Team movie.
