The author, from what I've read, is mostly a comic writer. There tends to be hints of humor in Daredevil runs, even just one-liners, no matter how somber the storylines get, so picking a writer who excels at humor makes sense for Daredevil.
This is all somber. I'd say it makes sense: the last ongoing series left Daredevil at a low point, physically battered for years - with no hospital visits, may I add, at least for the most part. I won't spoil specifically what happens, but an incident leaves him dealing with that ongoing physical trauma, possibly dead, then hey, maybe unable to walk. He has to painstakingly build himself up again.
But Daredevil series are a matter of finding new low points for Matt Murdock, and there's always been that hint of humor, if not full out laugh-out-loud lines. (Almost always? I think Miller got a little more nihilistic, but for the most part this series was built on humor in the face of adversity.) It got to the point with the Netflix series that my sister, frustrated, said 'it's like Supernatural, but he gets MORE shit thrown at him, and it's even more depressing.' (She also knows a bit about the comic book series, so.... I'd argue that the DD series may not live up to the river of shit known as the lives of the Winchester brothers, but, yes, he's got them beat in the comic book series. I'd also point out, as a matter of pure pride, that I could school her on DD. But I'm a DD fanatic. And yeah, a man tried to out-nerd me on DD based on the movie. When I rattled off pretty much his whole comic book history, he pretty quickly was awed at how much more I knew.)
So I was pretty shocked at how humorless this was. That isn't to say it bad; my star rating proves that I loved this. I'm still hoping this gets funny at some point; Zdarsky does funny so well that I consider him mostly a comic writer. (A writer of comedy as opposed to a writer of comics. It's pretty unfair: he does other things quite well, his strong point to me is just comedy.) Shocked - and pleased. This put Matt through the wringer, but I'm hoping things get better for him, and it was just flat out well done, a pleasure to read after the new Man Without Fear mini-series.
