I saw it Thursday before opening weekend with a crowd who wanted to be there and it was absolutely nuts, and then the next day I saw it opening night with a bunch of high schoolers in my showing and it was a blast. The answer I wish I could give is The Substance because I cannot even fathom how insane it would have been to witness and experience that fucking movie with 30 other people.
I was lucky enough to see the premiere of it at Sundance for their midnight showing. I knew nothing. Ari Aster introduced it and apologized for it not being totally finished (there were a couple scenes where they hadn’t edited out strings and stuff). I couldn’t get it out of my head for a month.
