True, it is slow moving, but the guy who plays him does a decent job of acting, considering how little he actually talks. I think non-verbal speaks more than verbal, and being able to act non-verbally the way he has, IMO, he's doing a decent job.
From the looks of it, this show is supposed to be a mystery and they will eventually reveal who/what he is. On abcfamily.com they have some sort of mystery game connected to the show too.
