The movie is "The Butterfly Effect" meets "Chronicle & The Craft." A group of high school teens discover the secret formula to time traveling and use it to their advantage. Rules are set and broken, but overall this movie is a pretty good tween movie.
Jonny Weston is the lead, and it's hilarious he's trying to play a nerd when he's a former model. But he has decent acting chops. Sam Lerner who plays his friend is giving me Miles Teller big time.
I would recommend. The movie does go by a little slow in the middle, but otherwise very good. I'm actually shocked it did so terribly at the box office.
