Gravity is a really excellent movie in my favourite genre (space), and you should go see it.
Overheard initial conversation coming out of the theatre was stuff like "When I stood up, my legs were shaking, like I was in zero G haha" and "I'm dizzy; I wasn't breathing for half the movie." and "I had to go to the bathroom since it started."
These are actual quotes, as nearly as I can transcribe them, which I think says a lot about audience immersion in the movie.
