I actually felt this was a really smart way to tell this story. If you do not know anything about the real story behind these characters, than its possible to watch the previous episodes with a real interest about the prison escape and almost see their point of view and need to get out. You know they are in jail for a good reason but its more theoretical than visceral as we don't really see them as particularly violent during this period. Especially Sweat is portrayed very low key and we are so used to killing in TV series that we become a little numb to it. The way they spent 14 minutes showing us how nice and decent the traffic cop was until we felt like we knew and liked him and then watch his stomach churning brutal and cruel murder, brought home who Sweat really was in a way that prepares us to really want him to be punished in almost a personal way. As Matt was already quite repulsive in the first episodes, what he did and how, did not need as much time. I feel that if I had seen these scenes in the first part of the series I would have simply stopped watching.
