I say this because Bruce Campbell confirmed that Ash will no longer be in any movies, so will Sam Raimi just decide that DbD is cannon to the Evil Dead?
I'm not saying no but I'm not yes either. Because most licenced characters lore are not cannon like the Halloween chapter and leatherface Paragraph. But its possible.
They said it was more like a movie cameo so I doubt it's cannon
Well yes, but actually no.
