I am very excited about the reboot! I think either it's gonna be great and we have more cool stuff added to the 'verse. If that's the case, awesome! Or it sucks, but that won't ruin the old show. If it sucks, we don't have to watch it, we can pretend it doesn't exist and still enjoy the original as we do now.
I am a 100% sure that it won't even come close to the awesomeness that was the original, but I'll give it a shot and maybe it will be good too, in it's own way. I would love to see the original cast involved, cameos or something. On or Off-Screen doesn't really matter for me. And if the cast isn't involved, that's fine with me too, as long as Joss is involved.
I have two requirements for the reboot, that I'll give it a shot.
1. Joss must be involved - Which he is so, "check" on that one
2. They don't re-do the story of Buffy with different actors - Which they hopefully won't do. Either they continue the story of Buffy Summers with Sarah Michelle Gellar (because she
is Buffy Imo, there's only one Willow and that
is Alyson Hannigan for me. Only one Xander, Giles, Tara, Spike, Dawn, Anya etc. No one can replace any of them
ever for me.), which is a dream of mine that I'm 99% sure will never come true. Or they do a new story, with new actors, set in the Buffyverse.
I have read (and heard in a YT Video) that some people have the idea, that the black slayer could be Nikki Wood. I have to say I love this idea

This was a coment und a video:
"Why make it a reboot? The Buffy lore is so expansive that they could easily make a Buffyverse with a Black female lead that fits the in with the original show. Imagine if it followed the story of Nikki Wood, the motger of Principle Robin Wood from the original show? 70's setting, young black girl in New York, then she becomes a young black single mum a couple of seasons in, all while trying to be a slayer etc! You could even bring Spike back, and probably even have Marsters reprise the role as the vamp make up could easily hide the fact that the actor has aged. Sure we know that it will end with the lead death, but the journey could be amazing."
And I loooove this idea!!! I even read that James Marsters said he would be interested to be involved in the reboot if Joss is involved

. I think this could be really amazing

And if they don't do the Nikki Wood story, but another slayer, I'll still give it a shot as long it's not another actress as Buffy.
