It gets...pretty bad after that, I'm afraid.
I thought one of the show's flaws was that it became too cavalier with character deaths. While I understand the appeal of not knowing if characters are going to survive each episode, early on the consequences of inmate deaths are profoundly serious. In the first episode Dino, the false protagonist, is murdered leading to a chain reaction of events culminating in a full-scale riot. This brings in the Feds, the Governor, an independent investigation (the episode with Charles Dutton guest starring, probably my favourite episode) and the resulting ramifications arguable impact the show til the final episode.
Halfway through the show's run however, inmates die and it's all, "Welp, them's the breaks," and everyone moves on as if nothing ever happened.
