It is one of the worst films ever made.

Rating: 2/10 (30 December 2013)

Indeed, the visual effects were very realistic and sometimes you felt like the movie was really shot in space. But that were definitely all positive aspects I can say about this film. The most important negative aspect for me were the characters. They were so unbelievably unrealistic.
Sandra Bullock/Ryan Stone: She is extremely unprepared for space (which can be seen in various scenes), is overly emotional and panics very often (which is very annoying and makes her seem even less suitable for space) and despite all this she still survives unharmed in the end, mostly because of luck.
George Clooney/Matt Kowalski: In contrast to her he is so exaggeratedly calm. This was probably meant to show his professionality but it rather makes him seem cold-hearted and inhuman.
This contrast seemed very made up and illogical to me. In addition to that, I could not empathize with Dr. Stone at all because she made so many silly mistakes you had no chance but to get angry at her.
Secondly, the plot advanced so slowly (if it even advanced at all?) that you hoped that in the next scene finally something interesting happened. There was so little suspense and nearly no progress that I thought about not watching the film until the end.
