Before it was cancelled, Prison Break was allowed to finish up their fourth and last season. This allowed them to wrap up all loose ends and tie everything together for one massive season finale. Last time I remember watching the show was in its first season in which they were actually doing what the title says; breaking in and out of prison. How it lasted this long under the same name is beyond me. After watching season 4, I think it should have been re-titled to something along the lines of the next 24 because that’s basically what it was.
