SPOILER ALERT
Just saw this. I thought it was pretty damn good. Reminded me of the show Lost quite a bit. People stranded with no idea what's happening is an interesting premise. I liked that the villains turned out to be Big Pharma, pretty ballsy in current year. Could it have been better? Yeah, but it was carried by the mystery aspect. I'm kinda glad the two kids survived at the end, but personally I would have ended the movie RIGHT after the "moment of silence" that the pharma company has for the latest round of victims. Instead we got everything solved in a neat bow and it felt...forgettable. End the moment of silence, have the honcho say "okay, back to work". Boom, end it right there and let you know that this will continue with no repercussions. That'd be a bone-chilling ending.
