My aunt, who was a forensic doctor, would be driven up the walls by the absurdity of the CSI screenplays. I'm an engineer and they manage to trigger me into laughter.

A bit is suspension of disbelief when some inaccuracy is needed by the story (like the sandstorm in The Martian) is tolerable, but completely messing up innocuous stuff you should have hired a field specialist to help you (physics, astronomy, police, medical, anything) with is inexcusable with the kind of budget even a lowly Sharknado has.

Seriously: I love movies. I was torn between engineering and cinema in college. Let's join together to never again have a cringe worthy moment on TV (unless it's there for the comedy value).
