I love most a24 films but there definitely are a number that the message goes over my head at times.
Honestly, I saw hereditary in theaters after all the hype it got and I walked out not disliking it, but just not understanding why it was so scary to people. I also went high as a mf so that could have played a role, but it wasn't until another rewatch and a breakdown video that i really starred to appreciate hereditary and the work that went into it with the cinematography and hidden foreshadowings and stuff. Now it's one of my favorite movies in recent years. Same with midsommar.
One that kind of had me being just "wtf.." was "men". The ending to that shit was so bizarre and had me confused on everything that had happened prior lol.
