Saw it last night on a conventional screen, not Imax. The picture was soft and grainy at times so not sure how it looked on Imax, maybe the projector in my cinema wasn't the best although I know Nolan shot this on film.
I liked it overall. I have been looking forward to it and it was definitely my most anticipated movie for the year.
Some of the visuals were wonderful. Loved the robots.
While I didn't love Zimmer's score on this one, it felt appropriate and delivered the right dramatic wallop to what was being shown on screen.
The volume was pushing my tolerance levels but it was ok, just hard to hear some pertinent instances of dialogue above all the din.
I won't pick apart any of the physics, I went into it purely for entertainment.
What did pull me out of the movie at times was the editing.
The rapid fire sequence of finding NORAD and then almost instantaneously launching into space with a bare bones briefing, no depiction of training, space craft familiarisation etc. just seemed to happen way too quick and was hard to swallow - bit like a chunk of the film was missing. It happened elsewhere too but that section in particular made me think what just happened?
Felt the acting was fine, there was a nice emotional weight carried throughout the film. Although I found Matt Damon's appearance a little unconvincing, possibly an unknown would have gelled better.
I think it's a film that needs to be digested and will reward repeated viewing...after giving the ears a rest.
