It’s hard to discuss this movie without engaging in spoilers. It’s a cast of mostly unknown actors (I vaguely recognized a couple of them) who are standing in a room. They realize that every minute or so, they must vote on which one of them is to be killed. There’s no way of knowing how many will have to die for the sick game to end, nor is there anything more than conjecture as to how they got there and who put them there.
I shouldn’t have liked this movie because it requires far too great a leap in logic. But I did. I certainly didn’t like the ending. It was trite and answered no question. Everything is left to interpretation.
But for some reason, I liked it. As always, YMMV.
