Query: A good start...

The first season of Buffy was definitely an exercise in bringing Buffy into her own. If you pay attention, a great deal changes with nearly every character between episode 1 and episode 12. Buffy starts off a little more airhead-y (and closer to the big screen Buffy) but she eventually moves towards the quick-witted punning slayer we've come to know. Angel starts out a little more cocky than you may remember - and a little less soulful. Its a good thing that Joss Whedon decided to make Angel a bit more sensitive than he started out, otherwise I'm not sure the Buffy-Angel romance would have worked. The differences in Xander and Willow are a bit less striking, but they're there. Buffy is a great show. It started off as a great show and only got better from there. Highlights of the first season include Xander turning into a hyena (one of my personal favorites) and Buffy's first death at the hands of the Master.
