This isn’t the best movie, but it was good, and much better than I’d heard. I thought they made some great choices about the characters that really supported the plot effectively. The acting is good. It’s true that it gets annoying for a while when Jodie is being hysterical for a long time, but that’s not the whole movie. In some ways it is like Panic Room. I think it’s worth seeing, though there’s no need to rush out and get it.
