Yeah, that’s sort of it, but I don’t think you can really dismiss this thing entirely. Like Buffy really was completely unlike other stuff at the time. It’s fully of sexist things but equally it’s interesting to note the whole “not as bad as X” aspect which is how most concessions to progression in the world of cinema and TV have happened.
So, yeah, it’s not much, it shouldn’t be significant but it really was, which is also a shame. But I’d imagine Buffy actually did a lot for normalising the notion of women in action Sci-Fi purely from being so incredibly popular. (I mean I think Xena was pre-Buffy but I don’t think it ever really got near that popularity.)
