Gravity or no Gravity

Clearly this is 'Open Water' but just in space. And the trailers are amazing and visually stunning but they are only 2 mins long. Can 'Gravity' with its star cast of Clooney and Bullock carry the 2 hour movie? I don't know, but its getting great early reviews. Im skeptical. Either way it seems like if you're willing to drop 10 bucks to see it, you should throw in $2 more and watch it in 3D, otherwise you can play it safe and just rent it. I feel like we may be seeing the best parts of the movie in the trailer, though Im sure there will be lots of drama and stress in the few mins after the drifting event that should make for a good watch. Its up to you. Im still not sure if I'll be seeing it in the theater. I don't see anything else worth watching on Oct 4th, so I just might go.
