Yes, this movie is awesome.

Rating: 9/10 (21 December 2013)

First of all, I wouldn't consider this is a Sci-Fi flick. This is a movie about the human condition. That said, the movie is indeed awesome - period. Many people disliked the movie because of a certain kinda hidden religious bias (in one or two scenes), which, in my opinion, doesn't ruin the movie at all. We all, as human beings, need some mystery here and there. Science is just another form of religion, after all. But that's not the point here - and I'm not a religious person either. Many people have talked about the special effects and whatnot. Right, they play their part in the movie. However, they are not, by far, what it really matters here. "Gravity" (and the title is extremely important) makes complete sense only in the final scene - and let me tell you why.
We have Ryan (Sandra Bullock's character) and Matt (George Clooney playing space-George-Clooney). Matt is only a side dish, and that's it. Ryan is what really matters. She shows us what it means to be human. In other words, what it means to live under all this "gravity". In space there's no gravity, no problems (in this sense), we run away, we float. Matt tells her that. In a nutshell: Space is easy (even after all the problems they had up there), Earth is hard. On Earth, gravity affects everything and everybody. Ryan lost her daughter - that's gravity. The final scene, in which she tries to stand up, fails, tries again and finally succeeds is what the movie is all about. The movie is, therefore, a metaphor.
We must live under the power of gravity: losses, deaths, problems, sorrow, sadness, longing, etc. etc. etc. This is what it means to be human. That's "gravity". In space, we will never find any gravity. Gravity is down here, and we must live with it.
