Books: let's go ahead and over-complicate this right from the start, my favorite novel is House of Leaves, my favorite book is Hot Water Music
Movies: The City of Lost Children resides here forever, but there are a bunch of other things I've seen since then that could occupy that spot if it wasn't taken
Shows: Subject to change too frequently, don't you know it's the new golden age of television? Presently Rick and Morty though, how great is it to be alive in a time where the best science fiction on tv is a cartoon about nihilism?
Music: See above, multiply exponentially.
Food: Easy, tater tots.
