For me, I really hate her humor. Granted, this just came from me reading her Domino series and its annual. The humor just didn't click with me, it felt really forced and annoying. Like that weirdly specific sense of humor a lot of female writers (and Ryan North, to a lesser extent) had during the late 2010's. Where it was trying to be nonchalant and fun, but it really came off as annoying and immature. Domino came off as a bit of an airhead, and it didn't help that the humor made her and her team sound similar at times. And it was jarring to jump between that humor and the serious, grounded story we were getting. Which was a shame, because the first arc's story was really good. And the annual had some bangers in it.
I know humor is subjective. I guess I wasn't the target audience for it. But for me, it killed a lot of my interest in the book.
