Alot of fans on this site say the he's their favorite character. People call him the only true variable. Some say he's the key to the show. Every one holds him in such high regard. I think he's a one-note character and a Kenny Loggins lookalike, to boot. "Penny! Where's me Penny? I have to get back to me Penny!" When Michael screams for Walt throughout the entire first season, people found it annoying. When Sun asks everyone and their mother "Can you help me find my husband?" in season five, people found it equally annoying, and rightfully so.
I personally hope he does not show up in season six. He found his girl, settled down and had a kid. Lets move on to more dynamic characters like Vincent(just kidding)
P.S. Henry Ian Cusack is a groper
