The worst offender I can think of is “Bohemian Rhapsody”. There is a scene where the record company exec meets Queen for the first time, and the frantic shots and cuts - what they focus on - make no sense whatsoever, creating a hollow tension to the point of being distractingly annoying. Shooting a regular dramatic scene like it was Michael Bay doing one of his headache-inducing Transformers action chaos sequence. Yet this mediocre thing won the Oscar for Best Editing, of all things!
