Excellent review, @namiks!
Happy to see COMIC BOOKS and graphic novels included as worthy of LITERARY reviews.
You go!!!
You write very well (a sign of being well-read).
This!

There are volumes which dedicate themselves entirely to the backstory and developments of specific characters within the narrative, though I felt that a lot of this was rather underbaked, to the point where the entirety of the story felt introductory and purely exposition. Constantly speaking of upcoming potential events or teasing those questions that have no answers, as if to imply that sometime, perhaps one day, it might start to answer them, though I was left having finished the entirety of Black Hammer without any of those answers.

I run into that problem too - but I'm from the 1900s, and I grew up on 19th Century novels that delve deep into everything.

Thanks for taking time to write a thorough and thoughtful review.
