Saw this at BFI IMAX last week.
Entertaining and besutifully shot, but the film can be essentially summed up to
tick, tock, tick, tock.... RUN! RUN!... tick... tock... HIDE! HIDE! ... tick... tock... tick... tock... BAIL OUT!!
It's a good action film and depicts the desperation of the situation well. But there is little development in any of it, and you don't really relate to any of the characters. It's more like a macro view of an event.
I am also unsure about whether I like an IMAX shaped screen, a square shape just doesn't seem as natural as wide screen.
No regrets about seeing the film, but also I don't view it as a classic.
