I really enjoyed this movie and the effort and hard work it must have taken for some of the scenes......I like the outer space element but it was predictable and didn't look realistic. Bullock's characters fear seems to lighten quickly considering her predicament. And the lines were a bit weak but for some reason despite all that I was totally taken in and liked it overall. Maybe I'm just to big a Bullock fan. I think seeing it in 3D would help the film but a bit of help with the lines would really improve this more. Clooneys lines as well. The overall effect was awe and amazement at the thought of actually being lost in space but as the movie went on my enthusiasm lessened. As did its believability. And predictability. Bullock was the only saving grace. Seeing her float around in a spacesuit is worth the price of admission.
