Ralph Fiennes' character is obviously portrayed as a disgruntled artist who's long since lost the joy in his craft due to the kinds of people he does it for, all of which seem to mirror some of the type of people you'd see in Hollywood; producers, investors, passionless actors, etc. Hell, Nicholas Hoult's character is basically the shitty fanboy who worships Fiennes' character but without understanding his work. The movie is almost like a director/writer's revenge fantasy after having forced to suffer these kinds of people, with the exception of Anya Taylor Joy's character who is the only one who seems to understand Fiennes.
Anybody else see the movie this way?
Edit: thanks everybody for the responses! I guess in retrospect a more accurate way of putting it would be that The Menu can just happens to work well as a satire of Hollywood. I didn't mean to suggest that it was intentionallly coded that way, more that one could interpret the movie this way.
