It's there. To paraphrase Anton Ego though, new things need people to stick up for them. So if you see a new story, go see it and tell your friends. Everything Everywhere All At Once is a great example. Amazing movie, and it's stuck with me.

I’ve heard so many good things about WH40k, but every time i search about it I get overwhelmed. Don’t know where to start. Any tips?

Dude I am 100% certain you replied to the wrong guy, because the only 40k stories I've read are Caiphas Cain books (which are pretty funny and entertaining).

Not really into grimdark though; when positive change is impossible I tend to check out and lose interest in the story.
