I just watch all 16 episode, and got to say I loved it.
If it would be to return, with all this Vampire pop-culture, this show would be a hit!
It would be watch by Vampires & Crimes show lovers!
It reminds me of the show Blood Ties (07-08), she the human was the PI.
But if it would be to return, I don't know know who'd play Mick, cause Alex O'Loughlin is now on Hawaii Five-0 (and doing great, I might add).
So that's my 2 cents! :-)
