I've watched in IMAX where you get the full IMAX experience. And I got it, image was OK, sound was OK. But still, the story itself - which would be an exciting story - was super boring. I never felt a moment of excitement. Probably Hans Zimmer's music didn't helped a lot in feeling this. Storytelling was also too much, repetitive scenes, events all over the story which makes you fell asleep. Perhaps was intentional, to feel that "foreverness of time" of the solders, but still, movies are about entertainment, and an IMAX camera is not enough for that.
