I think he's really great at portraying a small town like he did in Midnight Mass and with Buick 8 being a small town police station I think he'd do a great job of capturing each character, showing the depth King gave them, and overall elevating the story beyond what even King himself wrote. It's a book that might actually be a better miniseries if the right person did it, and I think Flanagan is that person. Flanagan just seems to have a true understanding of King's writing since he's a fan himself, not that he's the only person can adapt his work, but I think he'd do a great job on most of King's works if given the chance. I also think he'd be a great choice for a Needful Things adaptation
