Really, S2 was your favorite? Hmm. I liked it, but I did prefer 1 and 3 more. My favorite show of all time is probably Farscape, in terms of utter, consistent kickass quality, but Who would be up there for me. I don't know that Dexter would, it just doesn't gut me like the first two (or The X-Files, etc. for that matter), but I do think it's an AMAZINGLY GOOD show.
