Well, while we don't know any official plot details just yet, if Anya Taylor-Joy's words on the matter are any indication, it looks like the spin-off is going to lock in all of the right pieces of the Marvel books. Specifically, Taylor-Joy reassured fans of the Marvel comic saying,
I think the nicest thing about it is that Josh Boone, our director -- he's just such a fan of the comics, and he really loves them so much that he's really interested in just making sure that we do the comics justice for the people that love the characters.
