I think SNW is the perfect blend of both of these it "fixes" some holes and underdevelopments of TOS and doesn't set out to undo it* whilst standing entirely on its own as a wonderfully entertaining product in my opinion.For me, I don’t want past stories “fixed”. I want actual new stories with new thoughts driving them.
*Picard season 3 very much felt like an attempt to undo the previous seasons because Matalas was so attached to a fanfic he wrote 10 years prior.
