Before this film, in my opinion the greatest special effects of all time were in Avatar. Everything was so realistic, you could see sweat on their faces. This film not only trumps everything that Avatar has brought us, but I really don't see these effects aging for a long, long time. I could be proved wrong, you could see the models in Star Wars, the shark looks like a dummy in Jaws, but this might be different. I am a big fan of Cuarón's style as a director. I love the darker tone that he brings to his films, his point of view shots in his films are flawless. He went all out, he pushed the boundaries for not only what he could do, but what a director can do. Same with the acting. Sandra Bullock gives a great performance as Ryan Stone. If she was any lesser of an actor than the effect that this film had on us, would be lesser. Bullock is one of those actors that you root for every time. She has that charisma, you want her to survive. In my opinion, the most atmospheric and powerful moments of the film is when she is alone. This is a tremendous feat, considering she is in front of a green screen 99% of the time. George Clooney brings a likability to his role, his character was very entertaining and a relief, when the film was at its darkest. This is the movie event of the year so far, no doubt about it. If you haven't seen a film that you enjoyed so far this year, go see this film if you haven't already.
