Thought it was gonna be like a slasher flick, thankfully not. I didn't know it was based on a real story. Very in-depth characters. The guy is deceptively charming and has such a nice smile. You see the guys chumming around, having fun, joking, eating burgers. They were genuinely enjoying themselves doing what normal friends do. Then comes the strain on the friendship when the new guy is drafted.
Very well written and acted by all the guys. You see the difficult choice they have to make to join or become the next victim. You want them to survive, but you don't want them to kill.
Also makes you glad there is a death penalty for bastards like that.
