If you are bored with what Hollywood is producing, give this a try (if you haven't already....I am a bit behind the curve). Anyway, I found this movie to be creepy in a way that a cheesy horror flick will never compare. It also includes some physics nerdery, which is always a good thing. It will definitely keep your attention, because you will be working to figure everything out the entire time. Unfortunately, at the end, you will probably still be mind-boggled. But thats the fun part
