Chronicle is about three high school kids who come across some kind of mysterious artifact/meteorite and gain telekinetic powers. At first they use their abilities for kicks and pranks, like playing catch at 30,000 feet. But the least-popular kid, Andrew (Dane DeHann), becomes more alienated and convinced of his superiority. After Andrew kills Steve (Michael B. Jordan), one of the other two super-powered teens, the last one, Matt (Alex Russell) -- who argues that they need to set rules for how to use their new abilities -- must confront Andrew. All this is told via faux-video camera footage: Andrew is a budding videographer, as is Matt's girlfriend, Casey, and they "chronicle" the film's diegesis.
Let's get the bad news out of the way first. The plot sounds a lot like the setup to a Stan Lee Marvel Comics series from the mid-1960s, a fact you could probably glean from the promotional material around the movie alone. And yes, Chronicle is pretty much X-Men meets Carrie. But perhaps its real progenitor is the second Star Trek pilot, "Where No Man Has Gone Before" (1965).
