Have you seen the trailer for the new movie CHRONICLE? It looks pretty awesome, check it out:
Plot Outline: Three high school students make an incredible discovery, leading to their developing uncanny powers beyond their understanding. As they learn to control their abilities and use them to their advantage, their lives start to spin out of control, and their darker sides begin to take over.
From the trailer, it looks like some real thought went into it.. ie, how people would really behave if the same thing happened to them.
Can't wait to see it when it comes out. Release date is Feb 3, 2012. I hope it's a sleeper hit.
