I've watched it, and I'll never watch it again. Perhaps if I watched it in 3D I'd be impressed like most people but I find this movie shallow, two dimensional, even a little trashy. Believe if it weren't for A listers and big budget and special effects this movie would be just a blip. Acting is actually great, but story, dialogue, message of the whole movie is really weak. Also there are a lot of unconvincible, trashy things that I'd rate this movie watchable and 7 only if real astronaut explained it to me as believable. Strictly subjective, everything but acting was weak, story is shallow and quite stupid, survival, getting over lost. It's just a big fancy shiny wrap with two great actors doing their best and bow on it. Nothing more to it.
