I Liked it (surprisingly)... The story is nothing new, and the 'scares' have been done better in many a films... But there was just SOMETHING about it that made it an appealing film (the 'what' has yet to be discovered:) Biggest recommendation- don't view this as a 'horror' movie (not enough scares for that) and certainly not a 'drama' (not enough story/plot)
Better to bill it as an interesting 'what if' tale, and leave it at that... The nicest thing about the movie is a has something to say, but doesn't waste a lot of words saying it.
