I didn't get into Buffy until after the Musical episode(which I loved) and I was into it hardcore until the very end.
Whaaaaaat? Man I LOVED Seasons 2 and 3, my favorite version of the Scooby gang was when they were still in high school with Oz and Cordelia still around and Faith trying to fit in. 4 took some getting used to but was good overall and I'm halfway through 5 right now and it's been great.
