I am starting this review from one fact: I suffer from vertigo and this movie kept me in a state of tension for three quarters of the whole time.

The movie is overall visually stunning. The camera creates the depth needed for the outer space scenes and, at times, focuses on small details which become crucial to the development of the action. This visual device helped to create a sense of inevitability: you actually saw things coming.

The main plot is not particularly complex and the dialogs aren't either, but there are some narrative devices that suggest more layers of interpretation.

The two characters were convincing enough, Dr. Stone (Bullock) more than Lt. Kowalski.

I saw the whole movie not only as a thrilling story, but also as the tale of an emotional evolution and growth.

One of the best films I've seen in this late period, it still lacks something that would make it a true classic.
