This must be a joke that Arthur Fleck wrote, because I don't get it.
Horror movies throw a lot out there to scare us, but the scariest thing in real life is people.
Danny Boyle's 2002 film 28 Days Later understands this and makes the zombie film less about zombies and more about what lengths people will go to, to survive. That brings out the horror of reality making it a super tense film that barely slows down enough for you to catch your breath.
"L'Avventura gave me one of the most profound shocks I've ever had at the movies"- Martin Scorsese.
I think I could watch this film 200 times and never see the same film twice. Packed with subtle nuances within the shots, the dialogue, and even the characters actions. Director Michelangelo Antonioni wisely never reveals to much and instead keeps his camera at a distance, expect in a few stunning close ups that are the most telling of what's underneath but still keeps you wondering.
