We watched this on the giant IMAX in Braehead, and it was quite an experience. The three hours flashed past... well, I exaggerate, but none of us really noticed that the film is so much longer than your normal film.
   The special effects and world-building are amazing. The plot is okay  - just enough going on to keep the brain working. There was one shortish scene that I thought out of place, but I won't spoil anyone's enjoyment of the fil by mentioning it here.
   If you are looking for a world-beating extraordinary masterpiece, like Citizen Kane, you won't quite get that. But it's not far off, and well worth watching.
   Find an IMAZ if you can.
