re: Which TV show, IYO, has the most likable characters?

I nominate Twin Peaks, its' definitely got a high percentage of the total cast that is likeable to me. First off, the entire sheriff's department(Harry, Andy, Hawk, Lucy) is filled with likeable people, each in a unique way.

Then of course, Special Agent Dale Cooper, he's the most likeable one of all, by design. There's Pete Martell, Big Ed, Norma, Shelly, Audrey, Doc Hayward. I've probably forgotten a few, but that's most of them, hell I even like Benjamin Horn's skeezy little brother played by David Patrick Kelly, probably because it's David Patrick Kelly and he's just likeable in a "he has a punchable face" kinda way.

There's very few fence riders on Twin Peaks, I feel that all of the main cast are characters I strongly like or strongly dislike. The only characters I'm ambivalent about are minor parts.
