Absolute Batman. Its a pretty fun comic run so far. Its not profound or deep but its just a really fun book to read. I also just watched the entire Crisis on Infinite Earth Movies which those are fantastic. The love letter to the animation of the past and the care for the characters where they are up against the most dangerous of the multiverse but they never lose who they are. Love heroes stories like that. 

This is going to be an out there pick for media that I think comic/superhero fans should watch/read is My Hero Academia. It is the quintessential anime that cares for Superheroes. It is an anime through and through but it has an appreciation for the comics that came before it and Superhero culture that I don't think any anime has ever presented. In its purest form, it is about being a hero and what that means but deeper it goes to show how heroes affect the world around them and how their presence positively or negatively impact their world if they aren't careful in they use their powers. Its one of my favorites.
