The best part of the movie is easily the cinematography. The entire movie looks amazing from start to finish. Not just amazing, but better than any movie ever, even Pacific Rim. There is also minimum cutting and there are camera shots that go for a couple minuets, which makes the film feel completely real. Also, seeing it in 3D gives you an experience beyond belief. For these reasons alone I could highly recommend you see this movie in theaters. But the reasons don't stop there. The acting is amazing, just as good as 12 Years a Slave. The writing is also great. The attention to detail is unbelievable. The plot twist are plentiful and you don't see them coming. So much happens in this movie that you will want to watch it again immediately after seeing it the first time.
I've heard some people complain that the movie is too unrealistic, due to there being tons of debris flying around destroying everything but never hitting Bullock's character. Despite this fact, everything else in the movie feels entirely realistic. Also, the movie builds up tension so high to play on the audiences emotions of fear and excitement. The movie is an extremely visceral experience, so breathtaking and brilliant, it has become the best movie I've seen this year. So many parts of this movie are unbelievable, and I can't recommend this movie enough. 9.8/10 stars.
