3rd time. 3D, IMAX 3D, 2D.
3D is usually a negative for films IMO (except for Life of Pi, where it was magical). Same magic, here. 2D good, but the space scenes have real grandeur in 3D. Beautifully done.
Finally got my fill after viewing number three, but pre ordering on iTunes. Sure, it's derivative as hell, but who cares. Brilliant stuff. And compared to the last three -- miserable, ugly turgid pieces of crap, all three -- a masterpiece.
