Not everyone is into Buffy. I don't worry about it, even if I'm really close to them. I don't like all they like either, but different strokes for different folks (and I think things like mood, circumstance, and all that make a difference). As long as they let me watch what I want to watch, I let them do the same. (One reason for going online is so I don't speak of it to those who don't want to hear of it.)
For what it's worth, I did get a history teacher to try out anime in exchange for watching an equal amount of something she wanted me to see, and also promising that there was historical subjects (unlike many teachers, she's not burned out by the subject, only the job). She was so impressed by one that I even squeezed another short anime out of her which she had lukewarm feelings for (but said "still better than Disney"). It's worth noting that she sees no value in comics (other than a brief gag) or animation so this was no small accomplishment and I got more than I expected from her.
For me and others, commitment had to be small (that is only a few episodes, so season 1 would be easier to commit to than season 2). And I can't say whether someone should start with season 1 or 2. For me, I don't think I'd have gotten through the 2nd season had I not seen the first one as the first one made me care enough to get through the first few episodes of season 2 (and Buffy was hard for me to put up with in
When She Was Bad, I can only imagine how I'd have negatively reacted if I didn't know why she was that way). But I can see some seeing the first season as way too campy...but then if they like
The Lost Boys as many do then I don't think they have room to talk.
Oh! After I sat through
It's a Wonderful Life (pushed on me by the aforementioned teacher who felt it shocking that I'd never seen it before), I then tried to get her to see
The Wish. She wasn't into it, but being tipsy from spiked eggnog, I told the kids they could see it with me if they wanted. It was an easy sell to the boy, but the girl hesitated and said no, and in an offhand tipsy moment I said might be for the best, it's one of the scary depressing ones...and to my surprise that changed her mind ready to see it.
(They liked it enough that I played
Doppelgangland after, and soon after the following year I began a full Buffy rewatch--surprised I'd forgotten some episodes even existed--and they convinced me to buy the
Angel series which was my first time to see it with them. On a side note, while the girl liked both eps I played, she then wanted to see the Kim Possible Christmas episode which I happily got up...I remember thinking I was drunker than I realized at how I kept messing up with the buttons.
