I haven't read season 8 in a long while, but from what I remember:
Wolves At The Gate - enjoyed Dracula, Satsu and Dawn were great and I liked the Japanese setting
No Future For You - Faith's story was emotional and I enjoyed her actually making a friend in Lady Genevieve
Last Gleaming - Spike's back and Angel killing Giles was shocking.
The Long Way Home - good opening to the season, loved the Scottish setting, but not Buffy being so 'lonely'
Time Of Your Life - I know Fray is really popular, but I didn't find her, or the story that interesting
Retreat - nice to see Oz again, but hated those goddesses
Twilight - It's Angel and there's sex
Predators and Pray - don't remember this and would have to re-read to give an opinion
It was the shock factor that elevated the story for me. When I think of S8, it's Giles' death that I think of first (then the sex lol) I can visualise Buffy lying on the ground, too broken to move, tears running down her face. I thought it was so heartbreaking and meaningful.Maybe I need to read Last Gleaming again. I remember Spike coming back and the big final battle was good but I hate what "Angel" did to Giles. ..Even though it was interesting to see him try to resurrect Giles in Season 9.
