“Chronicle” is the story of three teen friends who discover some sort of glowing alien artifact within an underground tunnel. After a brief period admiring it, they’re overcome in some psionic fashion, succumbing to unconsciousness. When they awake, they find themselves endowed with burgeoning telekinetic abilities.
The object is not addressed afterwards… on their return to the site, the tunnel has been filled in. But the object is not the focus of the movie, it’s simply the catalyst.
Instead, what we have is the story of three young men suddenly infused with super-powers. How they would use them, how they would feel about them, and how they would keep things together between the three of them when their philosophies began to diverge.
