And that's okay. I think every DM should pick an adventure that calls to them, that they would feel comfortable running. For me, even going back to my earliest games, fey don't really interest me. (Heck, look at this chart and see how many fey rank towards the bottom of "favorite monsters" of the board members.

I also don't like dragons - I don't find them especially interesting. So I'm probably not going to pick up Fizban's Treasury or the upcoming Dragonlance stuff. Obviously I don't think anyone is wrong for putting dragons in their Dungeons & Dragons games, just as I don't think it's wrong to have a fey-based adventure. It's just not for me.
