Honestly sounds like you’re just depressed. I don’t even mean that in a mean way.
But not finding joy in anything is an actual sign of depression. Have some media standards declined? Yes, definitely. But by no means is literally everything bad now. You can still find plenty of non-formulaic media on streaming services.
Moving to something else that provides joy is a sign of healthy life, not depression. If you don't like modern media, you don't have to find some that you like, you can look somewhere else, in a completely different area.
Anybody with a big imagination must feel trapped by mediocre content. Daydreams are often more enjoyable.
