Though I tend to go for older science fiction, and, on top of that, from proven directors, two things sold this for me (and I ALMOST ended up seeing this at theatres as a result): John Goodman and J.J. Abrams--the first being solid in everything he does and the second with the Midas touch, especially when it comes to my favourite of genres. I really admired its originality. The cloying nature of the antagonist, the ambiguity of the unique situation and the way everything was tied together quite neatly left me both very satisfied as a cinephile and yearning for hopefully its inevitable sequel.
