Saw it Sunday...could not stop laughing. Forced drama; cheesy lines; and, instead of doing something different and letting the main character at least take control of one part of her fate (that is, choosing how to die when one knows it is inevitable), they bring on a delusion and, of course, since she tries to live she succeeds...because, after all, everyone knows if you try hard enough you get what you are striving for (even if that means surviving the most ridiculously absurd scenario imaginable).
Gravity had an opportunity to make a pretty profound statement, yet that would have pissed off the audience. Instead, they cashed out and produced another canned movie about perseverance.
I will say the special effects were phenomenal, though.
