Things don't really go to plan for anyone when the ATF decide it's time to raid the church compound and a simple story of religious child-murder turns into a big gun fight.
No one, with the exception of the essentially decent and naive young lads, comes out of this looking particularly good. The religious nutters and the law enforcement both justifying terrible acts as a response to orders from a higher agent.
The performances are all superb, especially Michael Parks as the head of the church, a far too believable example of mentalist wibble-thought inspired by a two thousand year old book. Glad that most Christians I've met are the fluffy, decent types who help out at homeless shelters and whatnot.
Anyway, film's excellent, you should watch it.
