Last seasons Buffy came way to close to porn a couple times for me to have enjoyed the season as a whole. Just because the network will LET you show something Joss doesn't mean you SHOULD show it. It's too bad because up until that point I had seen every episode and recommended it to quite a few friends for it's brilliant writing. Now? I'm a bit ashamed and hope they didn't take my advice.
I can only hope Joss got it out of his system and goes back to writing entertaining character interaction that doesn't involve graphic sex.
