If these people were real
Never realized how badly some of the characters behaved on this show. I really do enjoy the show, but man I would not want to be around some of those characters in real life.
First you have Sam, who is a womanizer. In general that's totally fine, you do you. But his inability to take no for an answer borders on sexual harassment at times.
Then you have Diane who is emotionally abusive. I mean, I just can't see constantly calling the person I'm dating stupid. She's just so contemptuous. Not to mention how she has to try to be involved in and control everything because all those less evolved people couldn't possibly get their own lives right. Also, there's all those mind games she plays with Sam.
And then there's Carla. Actively taking joy out of getting her "friends" to make terrible choices. She displays pretty regular bouts of rage and aggression. She also keeps popping out kids with whoever will sleep with her, and expecting sympathy and support for her hard life.
Later you get Rebecca, the gold digger/stalker that just can't seem to get her life right.
Okay, rant over.
