LILLY FUCKING MAY! Hate her dumb ass country bumpkin, lying ass. She was a lousy mother and I wish Val had told her to swallow bleach and piss off. I never saw her worth.  She did one good thing by running down Dianas rat boyfriend.... what else? Nothing 
I nearly laughed when I found out everyone, apparently hated Diana. My mother said she stopped watching the show because of, "that miserable brat daughter of Karen's." 
Was she always intended to be so unlikable? I realize they needed an opposite for Karen, but lawdy Christ, what a pain in the ass. I haven't seen the series,  3rd season onward in 20 plus years and I'm about ready to watch again.  I know I'm in for a world of annoying Diana by S4. 
Some of the later additions were garbage.  Ann, Greg's dumb ass sister,  her daughter and yes, PAIGE. 
 The Wards. Never gave one shit about either one.  Glad they left. 
Micheal was always a dumb ass kid and even though he grew into scorching  eye candy, his acting was shit and his character dead end. 
Mac- although he did become an important character, never felt anything for him as I did for Sid, Gary, Val, Abby, even Richard.  Never wanted him to leave, but didn't care either way. Never felt him and Gary would be friends in any scenario.
