I really enjoyed the first two episodes. I liked how Dexter's missing inner dialogue, that is very essential to the character, provides the necessary insights into how he has managed to suppress his dark passenger for so many years. Dexter was always good at creating a fake persona that to other people appeared like a "regular" person, so it makes perfect sense that he has managed to blend in so easily. I have read several reviews saying that they hate Debra being Dexter's new guide and that every scene with her is uncomfortable, to me that's kinda the point. She symbolizes everything bad that has happened because of Dexter's darkness. "Harry" as a guide functioned as a reminder of the rules he was taught, he got Dexter to only kill bad people, but that's not the role "Debra" is intended to fill. You are supposed to find her presence unbearable because that's how Dexter feels too.

Overall I think it will be a great season, the writing is good and the actors, especially Michael C. Hall, are excellent.
