This show should have been called "Under the Stephen King Trope Generator." Biggest problem I have right now is with the rapey teenage kid.Was that a plot thread we really needed in the show?
Definitely don't read the book, then. That particular plotline is even more weird and gross in the novel, because...
Junior's girlfriend Angie and her friend (Dodee; the heavyset girl from the radio station) are killed off by Junior very quickly and he keeps them in a kitchen pantry with others bodies where he molests their corpses repeatedly throughout the book.
