I came across an article where the lady who is in charge of the upcoming Supergirl movie said that the character is "too optimistic" and she wants something dark and gritty. I know it is beating a dead horse to ask "Then why don't you make your own stuff if you don't care to research and respect the source material", but this is just a small symptom of a massive problem.
I remember a normie friend calling me a nerdy snob because I refused to watch the Obi-Wan show due to the showrunner saying it was a priority to have Leia in it along with other stuff (I had already cancelled Disney) or I was told I was making a mountain out of a mole hill when I thought it was dumb in the 3rd season of Stranger Things to set up that guy and girl in the ice cream store to be a couple only for her to say she is a lesbian.
Like I said, this is all a symptom of a bigger issue but I do think it is a little sad that this is what I come to expect. Dark and gritty can be good every now and then, but would it kill modern entertainment to make something uplifting and hopeful? I know it may be sappy but I still enjoy watching old episodes of Leave it to Beaver or Little House and seeing the family unit celebrated.
If you look at games released, it seems to have been around 2009/2010 that things started to go sideways.
