What aspects of Season 6 do you think could have been altered or improved to make the season more of a successful experiment than a failed one?
I wouldn't say I was "dissatisfied" overall, but there are still some elements of Season 6 that were rather large mis-steps, IMO.
Some of these I've summarized in a previous post, but in the interests of a more in depth discussion, I'll expand on a few and add a couple of things I didn't care for.
1. Perhaps my biggest problem with the Season might have been how they broke Xander/Anya up. Granted, Xander's family had issues and Anya's "family" were a bunch of vengeance demons, so the wedding itself was always destined to be a disaster, but the way they just ended the relationship like that really bothered me. As
DevilEyes correctly points out, this misstep would not have been such a big deal had they reconciled in Season 7, but the fact is, they didn't. My problems with this choice is that it as lazy writing....it wasn't an organic place to go with the story, they forced it to go there to artificially stir the pot in order (in their opinion) make things more interesting. It also speaks volumes to what the writers thought about anyone in the Jossverse's chances were to end up with someone you love and happy.
2. The magic = drugs crap. Seriously, not until they one-up themselves in Season 7 has such a storyline been pulled from someone's butt-cheek as this storyline. In Seasons 1-5 magic is treated and talked about how most people understand the concept of "magic".....a dangerous, but powerful responsibility, not to be taken lightly. However, for whatever reason they decided someone needed to go through an "addiction" storyline (which I thought was a good choice in theory) but decided to co-opt magic for the season as the metaphor for drugs. Completely unprecedented up to that point in the series and Season 7 wastes no time redacting the groundwork laid in Season 6 by reversing this mistake. Biggest problem here: Inconsistency with in-series continuity.
3. I could never *really* buy Buffy sleeping with Spike.Could be that I'm in the middle of Season 4 and it seems like such a reach from where the character are at, but it just didn't seem believable to me. Granted, they did establish that Buffy had a dark side and that the "demon" in her influenced who she was becoming, so I suppose one could argue the merits of their relationship from that angle. And yes, I know she tells herself she was only sleeping with Spike to feel something, anything, but surely Buffy could have found someone a bit more reasonable to scratch that particular itch if that's what she desired. Not a huge quibble with the season, but still.
I've got a few more thoughts and nits with the season, but overall those are my main complaints.
