A Buffy reboot?
A spin-off maybe, but a reboot? Hmmnnn…
If so more Anya, please.
Goddammit. Just do a sequel. Ignore the “canon” comics and do a series focusing on one of the activated Slayers (or a group of them) from the last season of the show. Original cast members can pop up now and again if desired, but you can do so much with the way the last season left things open - you could start fresh with an entirely new cast and it wouldn’t even require being familiar with the original series.
That or just say fuck it and do a Fray miniseries/movie.
