The entire point of this movie...
is that most people are sheep.
shareActually, most people miss the point that the caller posing as a police officer is the real idiot.
Focusing on the staff and who did what and why is fine, but don't forgot the disgusting excuse for a human being that woke up one morning and thought this was a fun thing to do with their day.
Anyway, I thought this movie was great. Although somewhat flawed it was engaging because it raised awareness about the real life events and makes you think and talk about the subject matter. Most films can't even boast that.
