Before I started watching this movie, I had high expectations. Reviews and friends told me to expect a real science fiction movie. I've been longing for a real sci-fi flick since "Close Encounters of the Third Kind", "Contact" and "Sunshine". I know people nowadays are calling fiction and fantasy movies sci-fi, but I rather tend to draw a dinstinctive line and emphasize on the word "science". That being said, the plot is simple, but at the same time realistic. The movie tells the story of humans trying to survive in an utterly inhabitable place - space. It's a movie that will remind kids (and adults alike), spoiled by the strange education they receive through contemporary media, that not everything can be achieved by wishful thinking. Humans are not made for living in space. Every step off earth is a step defying nature. Is that bad or good? That's a decision everyone has to make for himself. The visuals are stunning. I watched it in 2D and I plan on watching it again in 3D. The spectator has the feeling to actually be there. At least as important though is the sound. Many filmmakers make the mistake of having sound in space. Of course that's totally ridiculous. The only sound there is, is the sound that's created inside of your space-suit or space-station by the shockwaves that hit it. Throughout the movie I had the feeling they got it right. And actually it didn't make the movie "empty", but quite the opposite, more tense. It intensified the feeling of "this is not a place where I belong". There was one scene though, I thought wasn't right. When Bullock holds on to Clooney, Clooney should already have the same trajectory as Bullock or the station or he should bounce back. I just don't get what's still pulling him. I think it is a mistake in the movie and a serious one at that. Anyway, I can overlook that, since the rest of the movie is very good. On IMDB it has a rating of 8.2 right now. I'd give it more like a 7.8. Maybe even less. I guess the rating is a bit high, because for young viewers it is a new experience to see something realistic on the screen. Should you watch it? Yes, definitely. Should you rewatch it? Maybe, for the CGI and if you haven't seen it in 3D. Certainly not for the story.

I thought the movie was decent, but no where near great as everyone says. It's very predictable and yes the CGI is great but does that make the movie?

I closed my eyes for 5 seconds and prayed a xenomorph would pull her out the airlock

Low ratings are from people who expected a hard sci-fi thriller, rather than a powerful drama set in space.
