But would it really be worth it? For one thing they absolutely decimated Angel to the point where if you are going to take his comic storyline seriously, even simply for the sake of continuity, I don't see them being able to get past the magnitude of the Twilight arc in a believable way. For another, they've been pinballing Buffy between Angel and Spike since Chosen. Would Buffy eventually getting together with Angel even hold any meaning anymore?
Well this is a tough question. On the one had, I agree that the Twilight arc was an assassination of Angel's character. I am really not one to be defending the comics, I dislike them, when I read them I'm like ugh why am I reading this BUT I do think that they do a decent job with Angel in the Angel and Faith comics. I like Angel much more in the comics than Buffy in the comics. And in A&F they address the Twilight issues, you see Angel at least trying to make "amends" (sigh.... yes again....) for the crap he did. And by the time you get to BTVS Season 10 when Angel crosses over Buffy seems to be in a good place with Angel, she certainly has trust issues to work out with him but she accepts his apology and she isn't accusatory. The fact that he went through what he went through to bring Giles back probably does some to redeem him from the Twilight arc. And then we aren't really sure how much of the Twilight stuff was his doing and not the entity that possessed him?? I prefer to not think about the Twilight arc to much because my head will hurt.
With regards to bringing Buffy and Angel together, I have said it before and I will say it again, it would NOT be a walk in the park. In fact I think there are some great stories to tell. I think Angel and Buffy would fight, I think they would have a difficult time adjusting to being around each other on a daily basis in fact and I think it would be a very interesting story to bring those characters together again after so very long. So it would be worth it to explore if the characters, who appear to still love each other, could even stand each other. Maybe much of this comes from the fact that I still read the characters based on the shows and not on the comics but to me, the only other person in the world that really understands the burdens and responsibilities that Buffy faces on a daily basis is Angel. Because he feels those same burdens and responsibilities in his work. They have both sacrificed so much for the world, including each other. So allowing them to be together at the end after all of the struggles would certainly mean something, it would mean that maybe it was all worth it, and maybe the hero (hero in this case is BOTH Buffy and Angel) gets their happy ending. But then again not every story is a happy ending.
