RealD

I have always thought that the concept of 3-D movies was cool, but in the past they never really caught on. Now, with the new wave of 3D movies coming into horror films (My Bloody Valentine) but more prominent in animated films, it seems they are here to stay. Having seen a couple of 3D movies recently, I can say that it does add quite a bit of depth to the story being told on the screen and definitely worth checking out!
