Although I have to admit that it's easier for me to watch the early seasons as opposed to the later ones. The later ones still touch a lot of somewhat raw nerves where watching the the early seasons is far more LOL!

That said, I think the earlier seasons are coming off a bit more dated. The latter seasons being a bit more epic-urban-fantasy-ish/internal angst oriented makes them seem a bit more tireless. The earlier seasons look very "high school in the 90s" now. Which, while not bad (especially if one was in high school in the 90s and thus it brings back war,m squishy memories) makes it seem very time specific.
