How did you find season 1 "silly"? Just curious as to your take thats all.
Silly as in, they were trying to throw every buzzword they could into every episode. Necrophilia, rape, child rape, lesbians, incest, midgetporn, breastfeeding a grown man, etc. It's almost as if a horny/dorky 13 year old was writing it.
They toned it wayy down in season 2. There's still some of it, but it's not as in-your-face. They're focusing on the characters and the story more than trying to "shock" the viewer, which is good.
