I don't understand why Greg has to sabotage Dharma. If she wants this car, why isn't that fine? A lot of sitcoms feature this kind of storyline where one character tries to undermine another constantly, but I find it a little depressing, which is why I watch D&G - it's generally got a more positive view of the human condition.
I love who is egging the Montgomery's house! It's complicated, liking D&G. I like the ideas behind the show, but sometimes they just don't go far enough. I guess it's what you think the show is about - is it about a normal/nerdy Harvard grad and his attempts to cope with his wacky spouse? Or is it about people learning to see a broader spectrum of possibilities in life?
