Waaaaay too much detail. This unbelievably tasteless episode manages to be both creepily voyeuristic and prudish. So far this season we've seen Buffy's rather conservative views on alcohol - now we get Bonking is Bad.
Consequently we get to see an awful lot of Buffy and Riley in bed (Typical quote: "Uh! uh! uh! mmmmrrrrrr! uhuhuhuh! hrrr. uh! uh! uh!"), but also the Terribly Bad Consequences that all that nookie causes. And then there's the wall of orgasms (Typical quote: "Ah? Ah! Ah! Ah! Touch it!"). Daft.
That said, Anya, as ever, steals the episode. Every single scene with her in it is an absolute delight ("I'm having fun. Whooo-hoo.") and it is long overdue that she and Xander get to play hero. Actually, all the scenes without Buffy and Riley are pretty good.
