Your preferred aspect ratio? (If someone held a gun to your head and forced you to choose.)

Xavier Dolan's film Mommy is shot almost entirely in 1:1. I don't like the film very much, but the choice of aspect ratio doesn't have anything to do with that.

9:21 ratio

That's right. Vertical. And yes, I do enjoy watching the world burn.
