Brilliant and engaging. Much better than many movies that spend millions of dollars on especial effects.

I've watched this movie at least 20 times in the last two years. This is now my litmus test for women. If she can understand stand it, she may get another date. If she cant, then she needs to leave.

Toooootally blow my mind. It's really hard don't get lost (I did), but it just makes you want to know what's going on harder. It was really exciting. Great thriller involving quantum mechanics, and all sort of theories, each one well shown. Watch and see by yourself. ;)
