Honestly, my favorite season so far has been 6 because I absolutely LOVE the darkness it has! I thought 5 was good too; it had some awesome eps like "The Body" and was pretty dramatic itself. I didn't like S4 very much because the whole Riley/Initiative thing didn't appeal to me. Seasons 1 & 2 were okay I guess... S2 had some good serious eps like "Passion" for example, but these seasons seemed a lot less serious to me... plus, I didn't like the Buffy/Angel 'ship at all! I much prefer Buffy and Spike lol! Oh, and S3 was good because of FAITH!! That would be my favorite season if she had been in the whole thing. I probably won't like S7 as much because I heard Joss wants to lighten it up a lot. I happen to enjoy seeing Buffy all depressed! And not because I don't like Buffy, but I think the suffering brings so much out of her character... okay, I'll stop now since you all probably have no idea what I'm rambling about anyways 😉
