Whoa! What a fucking head bender of a movie this was. It sucks you in right from the beginning and just gets more intense as it goes a long.
It does leave a lot of questions unanswered but it sure is worth the ride!
I'm the same way and regret nothing. I have personal social contacts and YouTube reviewers who recommend plenty of content. I go into movies without any knowledge or expectations and love it.
One of my favorite experiences is starting the Substance, thinking to myself how pretty Demi Moore is and admiring her as an older woman, and then gradually learning what the film is about.
