Piper is an interesting character for me because while I want to see her prevail (change into a better person, get out of jail), I don't really like her, and she's not really done anything awful. I was going to write up a big thing, but JanewayRulz! has probably explained it better than I could.
Unrelated, but how the fuck is Dexter S8 getting a 71 Metacritic score? It's the worst written season of television in the history of the medium.
