I came across this sentence:
"That was the year the Twilight movie was going to come out, and the kids were agog with all things vampire." — Shelley Dorrill (From Merriam-Webster's definition of 1.Agog)
I did quick search and this quote apparently comes from an interview with the author Shelley Dorrill.
Since vampire is a noun this sentence struck me as incorrect. I would have expected "the kids were agog with all things vampire-like/vampire-related" or, more so, "the kids were agog with all vampire-like/vampire-related things".
Was the interview setting that allowed for a laxer interaction (but then, why did MW dictionary choose to put this as a paradigmatic sentence?) or is it indeed grammatically correct?
