I agree that "Dirty Girls" is underrated. I remember when the spoilers came out, everyone was already declaring it the worst episode ever. I thought the spoilers sounded interesting, and the episode rocked.

And Spike naked is never a problem for me. It seemed a lot more natural to have him shirtless since that's how he always sleeps. But yeah, Spike/Faith had no real chemistry, and the writers were trying way too hard to make it sexy.
