Plus shows like Tales from the Crypt weren’t purely comic book adaptations, I believe that one was mostly originals. Honestly I’d love to see other author’s horror short stories get the spotlight too.Creepshow only had 2 King short stories compared to three originals, and the sequel only had 1. I’d say only having King stories would defeat the purpose of Creepshow.
Plus there’s only so many Stephen King stories that would make good TV episodes.
