Let's go with the speeches: Spike in Beneath You, Xander in Potential, and Spike in (what was the title, Empty Places?). Or Spike last night for that matter. All contained enormous amounts of subtext beneath the spoken words. They were NOT (imo) just telling us things about the character-they were demonstrating things about them. And in the reactions of those listening, things about others.
Well, it would help to know what things you think were demonstrated. I like the Spike speech in "Beneath You," although I think it went on a little too long; I enjoy a fine Shakespearian madman. It shows me Spike's remorse and selfishness and manipulation by the FE, and it shows me Buffy's horror, guilt, and unwilling sympathy. But then, I have said repeatedly that my problems with the season come post-CwDP. Xander's speech in "Potential," again, I would have edited just a bit shorter, although I think I'm in the minority in that; as I recall, most people here found that an extraordinary speech, giving insight into both Xander and Dawn.
I think you mean the Spike speech in "Touched," since he doesn't have a big speech in "Empty Places," and you're going to have unpack the meaning you see in it for me, since I think it's an overlong retconning bore.
I haven't been told about Spike's redemption and Buffy's growing acceptance-I've witnessed it, from Buffy preparing to stake Spike in Beneath You to Spike holding Buffy through the night in Touched. Spike on the Cross. Buffy's reaction to the news Spike sired Holden. Spike's horror as he realized he was killing again and his recoiling as the FE made him attack Buffy. Spike standing up to FE Drusilla because of his faith in Buffy, and Buffy justifying that faith by rescuing him.etc. etc. etc.
"Etc. etc. etc." is precisely the response that is not helpful. If I saw the same etc. you did, I wouldn't be arguing with you. And I don't appreciate the snippy tone, when I feel I've been nothing but courteous to you. If you think I haven't been, I wish you'd say when and how.
As for the Spike redemption, I don't disagree that this season has given us Spike trying to be a good guy. My problem with it, as I've said before, is that it hasn't shown me enough of Spike being a *bad* guy. It hasn't shown me a struggle. All of the guilt and remorse we saw have been left to the FE's influence; soulled Spike doesn't feel responsible for attempting to rape Buffy or for having spent a year fucking with her mind and trying to drag her down into the dark to stay with him; he gets tortured in a few scenes, but that's not where this show really plays out its consequences.
Instead, it gives me Buffy yelling at Spike and Willow in "Get It Done" that they've been holding back, afraid to use their power. What would have worked a lot better would have been scenes where I *saw* them holding back, afraid to use their power. In "Older and Far Away," an episode I don't even like, I at least get to see that Willow is so afraid to use her power--or so determined to win back her friends and her ex-girlfriend--that she won't use magic even though she and her friends are in mortal danger. I didn't get a single example of that this season, even though Willow's fear of her own power is purportedly a major theme.
Or, to take another example, I believe you're one of the people who has argued that Giles isn't evil, just demoralized by the loss of the Council and/or possibly afraid he'll have to kill Buffy to destroy the First Evil. I think this is a great theory--but I need to see (or really have seen) a Giles scene which supported this grief and panic. That's hard to do for Giles, because he doesn't tend to confide in the Scoobies as equals, but it's still possible: you could show him having acknowledged that Xander or Willow or Buffy have grown up by talking to them honestly about his friends. You could have him mention at key points, in a distant and controlled voice, that that book they need for research is gone--when the Council library blew up. (And ASH could *totally* pull off that grief and desperation with just a look and a pause and a tone of voice; and if you wanted to underline it, you could have an awkward pause as the Core Gang look at each other or avoid looking at each other, unable to deal with Giles' grief.) You could have a scene of Giles alone, with a glass of Scotch, just looking grief-stricken.
You could have one of the Potentials mention *their* Watchers to him, even, since some of them seem to have been trained, and presumably their Watchers were killed by the First. That would kill two birds with one stone, allow Giles to react and the Potential to show some of the grief and desperation behind her panic and graspingness.
