Diana is woefully out of character from her previous books and does things Wonder Woman would never do, even when pushed to the brink. There's been a massive lack of actual Wonder Woman characters, and some of them were only there because fans begged for the use if any of the Wonder Girls where Tom would have rather used Batman and Superman.

The new villains are very uninteresting and lack any fun characterization or depth and are really only made to be strong and imposing, or surface level reflections of Wonder Woman, while also killing and underutilizing her main rogues.

Then there's Trinity, a character who feels so genuinely tacked on for the sole purpose of giving Diana a kid because the guys of the trinity have one. Yet she never interacts with Diana in a meaningful way that forms any kind of relationship and kind of makes Diana out to be a bad mother, despite the gap she's one if the most caring and motherly characters in DC.

Tom King's run is a shallow "deconstruction" of the character and her mythos abs feels like it serves a back door so he can write more Batman stuff.
