_To get real deep one must get real high._

That's what I think the movie Chronicle did right among many things.

It got you real connected with the characters making you understand them, sympathize and be one with them. It doesn't simply show you a group of friends that you will follow the whole film, you are part of the group. That is how immersive the experience was: When they're laughing you're laughing with them, in their moment of weakness it felt like you're part of the group, sharing the moment with them and when everything went out of control it felt like you were involved, truly scared for your life.

It felt so real that the moment it all fell apart it was very emotional. It felt like Andrew was your actual friend, and this friend is doing something wrong yet as his friend you know you can't blame him after all he's been through, you know it's his pain that's gotten the better of him, and yet you know you still have to stop him. You feel all this the whole time that the moment the spear struck him it felt like you actually killed a friend (not that I know what that feels like but you know what I mean).

It was very painful, ergo, very masterfully done.

In addition to that, the use of the First Person Perspective also amplified the intimacy as much as the cast amplified the experience. I'd say it's a masterpiece of a film and if you're okay with taking advice from a random person from the internet then to you I say - Watch it.
