The more I analyse or read analysis of the show, the less I enjoy it. I can't just sit back and enjoy and episode of tv for what it is. In my head I'm deconstructing it. And what I find more than anything is that the more I tear it apart, the less I like it. Any of it. The writers, the seasons, the characters...everything. As well as that fandom got really not fun for awhile, to the point where it was a burden and that's just crazy to me, so I pulled way back.
I find this so interesting because I was always a bit jealous of those who analyzed the show and were able to put more insight into the episodes and characters. On my last rewatch, I tried to pay more attention to the show instead of just sitting back and watching, in hopes I'd be able to do the same, but now you've made me realize that it isn't such a bad thing. I'm fairly new to the fandom and developing more insight to the show sometimes sounds intriguing, but I don't want to end up critiquing it to the point where I absolutely hate it.
It's only happened to me once and that was after all the discussion about Season Six, I started to think that it was lackluster compared to the other seasons, and then I came to a point where I struggled watching it, and then I actually started wishing the show had ended at The Gift. I loved BtVS soooo much the first time I went through the entire series last year, including Seasons 6&7 even if I still preferred the first three, that I didn't really understand why I was suddenly struggling to get through a rewatch, but I think you've pretty much pin-pointed the reason.
I can only imagine how bad it was back when the show was still airing. Luckily, I, myself, haven't encountered anything bad enough in the fandom to where I'd want to leave.
To answer the original question, yes, I'm still a fan. The comics are a tricky thing for me. A few months ago, I was one of those arguing the canonicity of it, but now I've embraced them. Still though, I find it hard not to separate them from the actual show. My original argument of not reading S8 and After the Fall was the fact that the actors themselves weren't involved; Willow (or whomever) wouldn't invoke the same emotion on paper if she was crying as she would if it were onscreen. Basically, I wouldn't be able to "feel" the story like I could on TV. And, even though, I'm "good" with the comics now, those reasons are still why it's never really "clicked" in my head that Season 8 is 100%, no questions asked, the official continuation of the show.
Do I still wish BtVS/ANGEL had ended with Chosen and later Not Fade Away? Yep, I sure do. (Unless they were going to make more televised seasons)
But, the comics are here and they're official, so I read them. It may never really click in my head like the TV show does, but they're there anyway and I've been highly entertained by them, even with the latest issue that has many completely flipping their lid.
Although, maybe S8 didn't invoke enough emotion from me because I was so spoiled by everything happening. We'll have to see with S9.
