well, the usual knock on it is the gay shit that SOMETIMES happens (although there are 2 guys that are regular gay lovers, but anyway)...if you can get past that, it's a very good show with awesome characters and great storytelling...but hey, it's prison, buttfucking is bound to happen and to my knowledge there are only 3, maybe 4 scenes over the course of 6 seasons that actually shows buttfucking...
