Grady Hendrix - What am I missing?

I recently started Horrorstör, a book that's been on my To Read list for a long time. I love the general idea, haunted IKEA...sold. I, generally, like irreverently toned fiction. And I love weird/horror vibes. But I am several chapters in and the writing feels...almost cringily bad. The dialogue is juvenile. The only people who are described physically are minorities (which feels slightly problematic on its own). And the pacing is incredibly slow.

I promise that I’m not trying to slam anyone's favorite author or book, I'm genuinely confused. I thought this would be a slam dunk read. Did I pick a bad one to start? Is the author an acquired taste? Do I just put it down and move on?
