Inadequately researched, distracting TV commercials

I'm nor sure why the culprits are always the writers and directors of commercials for pharmaceuticals. Probably a coincidence. Months ago a commercial for Myrbetric pulled this faux pas.This time it's Jardiance. The main character in their vignette is a female band director who looks like she's trying to fly rather than direct. She uses even, symmetrical arm flapping movements to "lead" her band. I have no idea if the medicine is causative or not. But I do know that virtually every instrumental musician has to wince every time the commercial is aired. No conductor or director would want to be portrayed this way.
