There wasn't a single weak episode in s4. S5 had a few. I also didn't like howSeason for was coo to me but nothing tops S5. Just too many goated episodes that I've watched over and over again. S5 Angel probably tops any season if Buffy as well.
The Angel vs Spike fight in season 5 might be the best fight in the series
the cast got swept to the side for Spike.
