Aside from the fine acting, unbelievable visual effects and sound, and the high doses of suspense, what I really liked about this movie is that it didn't give into any chiches. It could have easily had corny one liners. There were characters in the beginning that could have made sporadic appearences throughout to provide comic relief. I could get into more, but I might ruin some of the plotline for those who haven't seen it. But lets just say that it was a very straight-forward film with very little dialogue, lots of great camera work, and almost nothing in the bullshit department. This film could have sunk at any given moment, but it didn't. I really respect that.
