People never use toothpaste

I'm a submariner. Most depictions of submarines - especially with giant wall-to-wall windows, super dark interiors for no reason, diving to stupid depths, taking a full-on torpedo or depth charge without any consequence beyond shakey-cam, and putting stupid down-angles or up-angles when diving and surfacing.

I hate when the protagonist start hearing/seeing things that aren't there or just in any other way retreats somewhere deep into their mind in a way that makes them forget the world around them.

Ever since I saw a video about it years ago, I've found it hard not to notice the overuse of orange and teal in shows/movies that have been color corrected to death. It's gotten better since the 2000s, but you still have a lot of shows with washed out colors where everyone wears stone variation of blue, black, brown, and orange clothing.

The worst thing is, once you've noticed it, it's so hard to ignore.

When historical clothing is really wrong/modern. Like if the movie is of the 1950s but the fabrics are stretchy.
