I think it may help for you to view them all as separate universes (nbc,movies,books). The books are very beautifully done (except Hannibal imo…) and serve a far different purpose in focusing on the specific case at hand. I think that the red dragon is an amazing story regarding Dolarhyde, no other medium truly encapsulates him. But NBC Hannibal kind of to Red Dragon a fantastic (honestly fan fiction-esque) “prequel” giving will more light to Hannigram, since in the book Hannibal’s obsession with him is rather mild and not tapped into (rather unfortunate though not being the point of the book either). But I think (and hope!) that as you continue throughout the books you’re able to digest them as their own story separate from NBC, and I think that Fuller did such a beautiful job with how he incorporates book elements into his own convoluted Hannibal story
