"Oooh! A PowerPoint Presentation!"
— No one ever
Nobody likes a slide show. I don't even have to back that assertion up with evidence. It's a universal truth — like saying "the sky is blue", "the grass is green" or "The Mummy with Tom Cruise is the worst movie ever made." And if you haven't seen The Mummy reboot, I just saved you and you should be grateful.
It's as if there is some unwritten rule that says: if you do a PowerPoint presentation, it has to be measurably boring on a physical level.
