I had to watch Primer three times to fully figure out what was going on and I have 135 IQ. So that makes it above 135 IQ, but we don't know how much above. Since IQ testers are terrified to give out absolute scores and insist on expressing it as relative on a scale resetting the mean to 100, it's arbitrary bullshit anyways so I will just multiply the number representing the differential by three and claim that Primer is a 205 IQ movie.
Also while watching Basic I quickly lost track of who was who because everyone was playing a soldier personality and they would show brief flashbacks of them mentioning some of their names, then have the detectives talk about them for a half hour just mentioning their names, and it went through a bunch of theories while I was playing Minecraft on the other monitor, then at the end it pulled like three big twists each cancelling the other out. Since the movie was told partly in fake flashbacks based on interview narratives I never bothered to go back and look through it to parse out any possible clues to the actual solution you get in the end. So Basic could be 200 IQ or just the brainlet slip I suspect it to be.
Jacob's Ladder has to be a 120 IQ film because early 2010s /tv/ worshipped it for being symbolic and keeping them guessing or something.
