So,
penny_lane_42 made the mistake of asking me what it was about Spike in S7 that I didn't like, and my response seemed a bit excessive for just a comment. So, here 'tis, with caveats.
A couple things to keep in mind: first, I hated a lot of things about S7, like the First Evil (cosmologically nonsensical; largely ineffectual as a villain), the execution of the Potential storyline (unending claustrophobic slumber party), the Guardian (no set-up!), Caleb (introduced too late, totally one-dimensional, and had nothing to do with the larger theme of the season) and the overwhelming sense of DOOOOM that pervaded the season. I think my dislike of those things tends to bleed over onto things that I otherwise might feel neutral about.
Second, I've only seen the season once, so this is my holistic impression of the season and the episodes. My grasp of some of the details is weak, and since I disliked it all so much the first time, it's unlikely that I'll rewatch anytime soon. These are largely gut-level, Do Not Want opinions, so you're unlikely to talk me out of them, 'kay?
That said,
( stuff I didn't like about the Spike parts: )
