Honestly, I wouldn't mind watching another season of Original Sin
Just as the title says. I like that the setting is back in Miami, and Dexter is unburdened from all the baggage he carried from past seasons. I feel like I'm rewatching Dexter again but with fresh perspective. Kind of a New Game + so to speak. I like all the cast and dynamics.
Obviously it has to end before it gets too close to the days of S1, but I'm wanting to continue watching these characters for maybe 1 more season. s3 is probably a bit much.
