Holy dicks, Daredevil is so good.
I'm not a super hero guy, but Daredevil is awesome. I only checked it out because so many people on here recommended it. Totally worth it!
You never ended up checking out Death Note, did you Kezia?
What about Berserk. That's just pure, dark fantasy. No kids (except for random villagers), lots of blood and action. Characters are great. Has a very HBO feel to it
The first 2 OVAs (short movie / long episode) I think are on Netflix. The original show is 20+ mins episodes and totally worth checking out if you like stuff like Game of Thrones or Spartacus.
Edit - if you do watch Berserk, I just wanna warn you that it is VERY dark and has lots of dark themes like genocide, R-word, murdering children, and more on those lines.
None of it is glorified, but, just like in Game of Thrones, it's a part of their universe and the main character, Guts, has to struggle with those themes.
Also has a strong female character and a non-stereotypical bisexual character if you look for those criteria.
I am actually gonna rewatch Berserk because of this! Thanks!
