Too much media uses short cuts and rapid movements to ramp up your nervous system tricking you into a heightened state of arousal they didn't earn.

Go watch Ghibli instead of Disney. So much nicer to see it earned through plot than strobe lights in your face.

2001 is something many people didn't get on first watch then found they couldn't let go of in their mind after it was over. Kubrick IS messing with you. That pacing IS intentional. Watch "Room 237" about "The Shining" for an idea just how deliberate every bit of what you see in a Kubrick movie is.
