This is not my type of movie, though it does contain plenty of things exploding.
Gravity's about one woman's desperate fight to survive the harsh conditions of space when a routine maintenance turns absolutely deadly. I don't really keep up with actors and actresses too well, but I distinctly remember Sandra Bullock from light-hearted movies like Miss Congeniality. Gravity's a far different role. As Dr. Ryan Stone, audiences are treated to actual first-rate acting.
The story's way far-fetched and the plot's certainly out there, but at its heart, Gravity's a character driven tale of survival. The movie's screen time of 1:30 ish minutes fits it perfectly. There was one spot where I felt things were dragging a bit, but it was brief enough to not leave a total bad flavor for the film.
I'm not much of a drama type movie goer, but I'd actually watch this one twice.

(When I got to the end, I half expected to see scenes from the recent Tomb Raider game.)
