Tosh, don't waste your time. The plot isn't even worth discussion, and Sandra Bullock and Tom Hollander have gone down in my estimation for taking the money to do this film. This was more like "Lost" than anything else I've seen, with no explanation for what has caused this "situation" or why some "bad people" are on the side of the unknown "thing"... Shallow... I can quite see this becoming yet another unending box set. That may be your thing, but it isn't mine.
