The writing is so bad I had to check to see whether it was actually one of the teenage actors who'd written the movie. No, it's an adult. The dialog is stilted and facile, and the story alternates between weak and cliched.
The acting by the adults is appalling. Just because it's low-budget doesn't mean the acting has to be terrible. (See "Primer".)
And the cinematography and direction are terrible too.
This is a terrible movie - but don't blame the kids.
