By not taking itself too seriously, The Menu turns out to be a really snappy, sometimes absolutely hilarious, satire. Especially its fusion of dark humor and social commentary is very on point. The performances are brilliant, and the overall look is exquisite. Has a few pacing issues in the beginning and the middle, but the longer it goes, the messier and the better it gets.
Besides that, simply everything with Ralph Fiennes in it is worth having a bite of. The Menu has loads of good and interesting ingredients, but he is the one who makes the difference.
