I need to catch up on movie reviews. It's a few months since I watched Chronicle, I have to admit.
I had to read the Wikipedia summary to remind myself of how it ended. Not a good sign.
It wasn't bad to start with - 3 young men find something on an outing in the woods. It's a power source of some kind, possibly extra-terrestrial. They soon discover that they have powers - they can move objects, and as they practice, they control those powers better and they even become able to fly.
At first, they use their new-found powers for pranks - they are young men after all! But one of the boys develops a dark side (maybe it was always there?) and doesn't see right from wrong any more.
It ends badly, that's all I'll say!
