I’ve never read a Goosebumps book. I at least recognized some of the monsters; I remember seeing the book covers back in the old Scholastic book catalogs.
I suppose it’s the musical equivalent to being typecast; but I knew the music was by Danny Elfman almost immediately as soon as it first started playing.
It was interesting how much the R.L. Stine cameo felt like a Stan Lee cameo; that was what tipped me off that it was him.
It’s a bit odd having a fictional story about a non-fictional person. This almost ends up with a “Wes Craven’s New Nightmare” thing going on, in that I’m now inclined to believe that R.L. Stine’s monsters all escaped in real life and that this movie was written to seal them away again.
