Haven't seen the latest Dexter episode but it started getting better with the second episode, still not sure whether I'm liking the religious vibe that seems to be the theme of this season.
Thought the first episode of The Walking Dead S2 was quite good, but then again I've been burned a bit before with that series. I agree that the thing with the zombies not being able to smell them was kind of a weird change, felt like they changed their stance just to have that scene (donno if its like that in the comic?).
Oh also started watching Homeland, quite good so far~
