I gotta disagree.
I think S6 rocked. To me it was the highlight of the series. I doubt Buffy will be able to top that season again.
I admit, Doublemeat Palace was pretty horrid, yes. The Riley ep was, in true Riley-fashion, boring as hell. And the drug metaphor in Wrecked was about as subtle as a train crash.
But the rest was just plain awesome.
And season 6 had a lot more depth than the ones before. Let's face it, S1-3 was child's play. Sure it was funny and entertaining, but essentially it was your average teen angst show. It just didn't take itself too seriously.
S4 & 5 had some awesome eps but overall were fairly fluffy. (exceptions: The Body, The Gift and possibly Restless)
But S6 didn't pull any punches as far as character conflict was concerned. There were no easy answers for the characters. THAT'S why that season rocked.
Buffy couldn't just kill whatever pissed her off.
Xander couldn't just make a joke and be done with whatever was bugging him.
Willow couldn't just wave her hand around and get away.
And traces of this can still be found in S7. Although I feel as a whole S7 is infusing the series with more action/comedy again. There's more supernatural broo-haha going on.... (and one hell of a body count, so far!).. etc, etc.
Except for Spike's story-line it all seems rather... bland.
But let's see what else is going to happen this year.
No power in the 'verse can stop me.
