Alright, I like to call myself a semi-loyalist. Essentially, I think the best seasons of Buffy are 2-5, and that the REAL series finale was The Gift, not Chosen. I want to clarify something though - OMWF is still my favorite episode, and there are a lot of other episodes (Tabula Rasa, Storyteller, Normal Again, Conversations with Dead People) that I like from s6 and s7, as well as a few characters (Robin was pretty badass, and Andrew is incredible). I definitely still consider these seasons to be canon, and I understand that Chosen is the finale; but I still think it would've been better to end it at the Gift.
As for season seven, there's good and bad. Namely, good = Andrew + Anya, bad = Everything else. Honestly, I can't think of anything else from s7 that was consistently good. Buffy (the character) was annoying, repetitive, and very egoistic. Also, there's something that I can only describe through metaphor (specifically, video game metaphor). In Season 7, Buffy was in God-mode. It's as simple as that: She was never wrong. She grows outrageously as far as power goes, and, did I mention she was NEVER WRONG? Seriously, throughout the show I loved how Buffy was an empowered female, without needing everyone around her to be emasculated. This changes completely for season 7. It's like they couldn't make Buffy seem powerful without stripping away everyone else's strength.
Anybody remember Spike from season 2? You know, that badass vampire that was going to rampage through town, take what he wanted, for no reason whatsoever. The one that killed two slayers, yeah, that's the one. In season 7, he becomes a sissy. He no longer has opinions - instead, he simply agrees with everything Buffy does, not because he loves her, but because he actually thinks she's right. I can understand supporting someone because you're in love with them, but instead, the writers decided to finally murder Spike's character by stripping away his personality, making him Buffy's figurative puppet.
My other problem was that Xander and Willow's personalities got demolished. Xander had one incredible speech in Potential, but other than that, he sucked. No, really. He was the only reason season 1 was bearable: He was quirky, very funny, and I could relate to him. Now, all of that is gone. A few funny lines here and there, but overall, the writers got VERY lazy when it came to Xander in season 7. They made an even bigger mistake with Willow. Up until season 5, she would probably have been my favorite BtVS character. After that, she was absolutely awful. Not only is she not funny, witty, or even that smart anymore, she is also nothing more than a plot device. She advances the plot, and then the writers forget about her. What I loved about Buffy were the little moments - especially the funny ones. Willow and Xander were a big part of that. I think the writers just got so involved in the tons of extra characters and intricate plotlines that they forgot the fundamentals of the show's greatness.
Aside from that, there was a serious lack of outstanding episodes. (this is, of course, my opinion) Every season had at LEAST three outstanding episodes. Now, anyone that has read at least one of my posts will know I love to make lists, so here's a list of what I consider to be extremely outstanding episodes from every season (excluding 1, that was short and they were still finding their path):
SEASON 2: Innocence, Passion, Becoming pt. 1, Becoming pt. 2
SEASON 3: The Wish, Amends, The Zeppo, Doppelgangland, Graduation Day, pt. 1, Graduation Day, pt. 2
SEASON 4: Something Blue, Hush, Who Are You, Restless
SEASON 5: Fool for Love, The Body, Forever, The Gift
SEASON 6: Once More, With Feeling, Tabula Rasa, Normal Again, Grave
SEASON 7: Conversations With Dead People, Storyteller, Chosen
As you can see, season 7 is clearly the one with the least outstanding episodes. I know, a lot of people will say Lessons should be there, but I thought that, while it was one of the best BtVS season openers, it still wasn't that excellent.
This is my second major problem. Not only did a lot of the characters get skewered, but the amount of incredible episodes dropped considerably. So theres my two cents. Okay, fine, its more like a jar full of pennies (and some nickels), but there it is anyway. Congrats to anyone who made it through. For those without the patience, I hope my various bolded words and underlines helped a little.
