The issue is the intention behind it, if the intention is comic relief they might not add much to the plot, but generally are still relevant in some way and make the film more entertaining
I’m not a huge fan of poorly fleshed out characters in general if they’ve got any amount of screen time
If they haven’t got much screen time and aren’t fleshed out it’s even worse if the one defining character trait they have is that they’re gay, black, trans, etc etc
Imagine if some adventurers go into a tavern, they talk to the generic hooded loner on their own in the corner, they give the adventurers the quest as usual and then for some reason mention that they’re vegan or something, no relevance to the story and it becomes kinda obvious to the viewer that they were only given that character trait to check a box
Kaos is one of the good examples I’ve seen recently sorry if I already mentioned it, there’s a trans character in the underworld who was part of a female only Amazon tribe and was thrown out and eventually killed for transitioning to male, but they don’t even mention any of that until he’s already been well established for a couple of episodes and they do it in enough detail that it doesn’t feel forced
I’m all for representation in media I should clarify I just want it to be done well, there are a fair few good examples but also a good number of bad ones
Does seem that way
I’m not sure real people can be compared to fictional in that way, as your friend has infinitely more character because he’s a real person
If you were to ask your friend what his favourite food is, or what his opinion on pineapple on pizza is, or what he has for a desktop wallpaper he’d have answers for all of those questions or a reason he doesn’t have an answer
If you were to take one of these hollow characters I’m talking about and ask them that question the answer would just be made up on the spot
If your friend showed up in a TV show for 5 minutes just as himself in a situation he would realistically be in I can guarantee he’d feel real and natural because he is a real person with a history
