Sometimes referred to as a "film purist", the celluloid simp is an individual who maintains a very strong belief that celluloid film is the only way to shoot a cinematic movie. Despite being more practical, accessible, affordable, and modern than a thin sheet of synthetic plastic, Digital cameras will NEVER touch the hands of a celluloid simp.

A lesser variant of the Celluloid Simp is the Film Fraud: individuals who shoot movies digitally, but then proceed to degrade that nice, clean image in order to mimic the flawed look of celluloid film.
Tarantino: “Shooting on digital is like eating a veggie burger.”
Person 1: "Why does he hate digital cameras so much?"
Person 2: "He's just celluloid simp, that's all."

An alarming trend in Hollywood where classic movies in various genres are re-chewed by some worthless piece of shit hack who has no ideas of their own and puked up to audiences who either 1. Don't know any better ie. Didn't know that the movie in question is/was a remake or 2. Just don't give a fuck.
As of 2008 there were 172 acts of celluloid bulimia and the trend continues. We as movie watchers and lovers of these movies, or some of them, wish that Hollywood would get some help for their celluloid bulimia, or find someone with an original idea... and fast.
