Not the OP, but as an older guy, I'll throw in "Everything Everywhere All At Once". Very fast paced with incredible concepts being thrown in seemingly at random

Not the OP, but as an older guy, I'll throw in "Everything Everywhere All At Once". Very fast paced with incredible concepts being thrown in seemingly at random. When you reach the infamous rock scene, it feels like it's the first time in the movie you've had time to draw a breath. Also very confusing emotionally as you'll be laughing one minute and snivelling the next.
