I really dislike Season 7. Only one episode there ('Conversations With Dead People') is up there with earlier seasons' episodes in terms of quality, and I hated the resolution and ending.

I'll have to disagree with you about Season 6, though. It may be that it just came along at the right time in my life. I rewatched it when I was deep in the middle of an angsty quarter-life crisis, so I really identified with the Scoobie Gang's struggles in that season and found it really empowering.
