I don't know, I think a villain whose plan wasn't doomed to reasonably quick defeat because they failed to consider that there might be heavy artillery at the established Army base just outside of town is more formidable than one who underestimates a bunch of high school kids. And, when you...
And how, precisely, is being a giant snake without opposable thumbs going to help Wilkins take over the world? It'll help destroy a town or two, and then come the B2 stealth bombers with laser-guided fuel-air explosives. Or, if he attacks a major city, the armored cav with flamethrowers and...
I guess we just want different things in villains. I like the motivated villain, whose plan makes a twisted sort of sense when you look at it from their perspective. Wilkins was a nifty characterization, but what was next on his to-do list after "become a giant snake"?
Anya's purpose during the last season seemed to be mocking the writers. Which I'm totally down with; she was, really, one of the few positive characters by that point. And I'll never understand the affection for Mayor Wilkins; sure, he was quirkily identifiable, but his plan was stooo-pid. If...
I think it was more the cynical nature of it, like "well, I've been telling everyone how badass this threat is all year, so someone had better die, and I've gone to that well with Buffy too many times already". I'm not saying that a character death needs to be filled with great import and somber...
And he wasn't a soulless monster who had tried to murder and drink the very lifeblood of every other character (both individually and as a group) multiple times.
Yeah, it's just you. And about a bazillion teenage girls, apparently. Me, I fail to see the difference between Season 4/5/6 Spike and Jeffery Dahmer with an ankle bracelet.
Probably a contractural thing. Signing a "recurring guest" contract probably gave the actress more freedom to work on other projects if/when they appeared than signing on as a regular.
I think the explanation was that Mutant Enemy tended to try to have "up" episodes of Buffy when Angel was "down", and vice versa, especially when they were on back-to-back. The end of Buffy season five was the start of the Unending Descent Into Misery, so the somewhat goofy Pylea storyline was...
You don't need either to enjoy the other; even the crossover episodes work well enough on their own. Quality-wise, there is no reason to avoid Angel at all. It arguably surpassed its predecessor, and certainly had nothing like Buffy's less-than-spectacular final two seasons.
