Query: Lovable Psychopath

Who cannot like Dexter? He's the perfect boyfriend, a loving brother, the friendly co-worker who brings in donuts for his officemates. Smart, good-looking, funny...oh so what if he has one little character flaw? Ok, a big flaw. Ha, ha. But I dare anyone to say they don't like the guy. Michael C. Hall is an amazing actor who has managed to make a psychopath lovable. I love this show!
