I'm in the same boat as Mazy & Buddy on this one. I'm totally sold on the visuals. Robot, vehicles & space station designs (reminded me a bit of the ME's Presidium). Sound design was also spot on and sounded terrific in the cinema. But after seeing district 9 I had higher expectations for the story.
PS Hated Jodie Foster in this (what's wrong with her accent), but that South African actor really pulled off the crazy unhinged maniac.
