Here we go... Lots to write, opinions still being formulated. I'll head straight to my favorite episodes then move on to critiqueing in general.
Bargaining - Despite my disappointment in having Buffy being resurrected by magic, I found this episode absoloutely riveting from start to finish. Seeing Buffy's reaction to earth, in retrospect, makes complete sence. She was torn from Heaven, and to her this probably seemed like she skipped earth and went straight to hell. Meanwhile, Willow's spiraling begins (

). 10/10
After Life - Buffy copes, the gang copes and revelations are made. Buffy's scene with Spike is now one of my favorite moments of the show. Seeing her whisper her secret "in a dead man's ear" (to quote the song "Let Me RIP") is heartbreaking. Who would've thought that this whole time she was floating on Cloud 9? 9/10
Once More, With Feeling - Took a while to grow on me (I still think it is by far inferior to Xena's The Bitter Suite). I LOVE this episode, despite some dodgy songs (namely Spike's little tune and parts of the climax). The opening song almost reaches Disney-standard emotions, which is saying somethin'. 9.5/10
Tabula-Rasa - Incredible. Simply that. From pain to laughter to pain again, this episode really does pack the punch. 8.5/10
Smashed / Wrecked - Heartbreaking. Simply that. Willow's and Buffy's descent begins in these episodes. Buffy caves in to a moment of (rough and a not-so-reperable

) passion with Spike, and Willow takes a turn for the worst with her overuse of magic. 9/10
Gone and Far Away - Don't know why. Dawn is a whining little idiot that deserves to be treated like a child, but I still loved this episode. 8/10
Seeing Red - Best. Buffy. Episode. EVER. Everything happens and is done so splendidly. Spike and Buffy's final scene for the season is incredibly painful to watch, just because it's just so, well, real. Poor poor Buffy. And Tara... Oh Tara. I will miss her. The show just won't be the same without her. 11/10 -- Yes, that good. Haha...
Grave - Coming full circle. Buffy crawls from under the ground again, only this time with willingness to live in the world and show Dawn what it's all about. Xander and Willow's scene near the end is just so touching and it goes to show that they really can face anything so long as they're together. And boy, what a cliffhanger! Eiick!
Ya know, despite my dislike for Evil!Willow (I'm scared for the consequences of her actions), I was pointed out to something kinda nice and romantic. All this power and ability came about out of her love for Tara. It really goes to say something about Willow and Tara's relationship. 9/10
Random rants and thoughts:
* What a contrived way of breaking up Xander and Anya and having her reform to demonhood. Pathetic and unneccessary. Xander really started shining with her, and now he's back to being a whiny dork. Great. Just great.
* Dawn is just so incredibly annoying. Put a yap in it already! Yes, you were a mystical force for evil last year and I feel your pain for that, but jeez, you don't always need to call attention to yourself. Keep on stealing little girl, cause no one cares. I don't anyway...
* I wonder if Spike's going to be a tortured puppy like Angel now. Should be interesting to watch. He deserves a soul though. For better or worse, he's truly earned it. Bring on tortured Spike!
* Willow...

No Tara, now a murderer, tried to eliminate the world. I hope she manages to go through year 7 without too much pain. Still love her as if she were still that computer nerd from Sophomore year.
* More crossovers, PLEASE. I know the whole move to UPN made that a pain in the behind, but those little moments of get-togethers are sorely missed.
* Season 7 (and 3 of Angel) are on the way. I just couldn't wait. Any "preview reviews" are more than welcome...
* Oh, and Joss now owes me 2 new Slayers. I don't care what fans claim, in episode 6/20 Buffy dies momentarily. I want Slayers, and I want 'em now!
* The Trio - Why? Good god, why?
Thoughts, questions, comments?
EDIT: My season ranking as of now:
1. Season 5 - Glory + Dawn - Still holds some smart analogies to real life situations and the best season arc, bar none.
2. Season 6 - An emotional rollercoaster. Just lacks a bit of focus, and focues on the three stooges way too much.
3. Season 3 - Great arc, great additions to the Buffyverse (specifically Faith and Anya)
4. Season 2 - Great season in the grand scheme of things, but lacks an arc and some filler episodes are poor.
5. Season 4 - Wasted potential. The Adam sub-plot just screamed 'meh'!
6. Season 1 - Great pilot, great finale. Not much inbetween. Also, not a huge fan of The Master.
