Watched this a few nights ago, on recommendation from several people. I enjoyed this film – the premise was interesting (and rather terrifying, actually), and I did enjoy watching the story unfold. At times, though, I thought it moved a bit slow, and I didn’t really “get” the love story – not a lot of chemistry there, IMO. But, on the whole, it was a good film. I probably won’t watch it again, but I’m glad to have seen it.
