Start with the shakey cam effect, often added post production, which does what no human head/eyes do during fast movement.

(And often used to cover up poor quality fight scenes)

Second using an incapable camera person, the camera jumping around like my grandma doing video on her phone. Steady cams, and gear, and booms, are a century old!

While I am open to looking at all modern issues, I'd prefer getting rid of purposeful garbage first.
