The thing is this movie is so close to real life that it scares some people. It’s hard to imagine someone to be so heartless. They just so happened to have a psycho on there and that tall guy might’ve been unless he was really just following along with Zach because he didn’t want to get caught. People don’t get though they’re going straight into crazy mode because they’ve suddenly gotten in touch with emotions they didn’t have before. It’s like Lord of the Flies but not. Since the change of feelings/emotions was so abrupt. Although it was annoying how long it took for the good guys to win at last.
