I thought he was pretty cute - at least in comparison to the other guys. Don´t know, the Jack (boring) / Sawyer (annoying - at least in Season 1) / Charlie (even more annoying) / etc. types are just not my cup of tea, I guess.
I have never seen TVD, but that´s just because I dislike anything with Vampires.
Michael Emerson has more emotional depth in the characters he plays than most people have in real life.
He deserves the utmost respect.
