Great movie that falls apart at the end

This is on Netflix if you haven't seen it. It's well-written, with suspense that keeps you on the edge of your seat. It's a deep story that begs the question "What would YOU do in that situation".

A cheesy over-the-top Christian/conservative community had to deal with a serial killer and a kid thinks his dad may have been the killer. He sets out to see if it's true. Excellent movie that deals with a lot of underlying issues.

But the last 10 minutes or so it falls off the rails with unanswered questions that the movie didn't address. A few scenes or lines in the movie could've changed all to it. You can make an educated assumption, but the writer chose to really eff it all up.

Still. It's a good movie, worth watching.
