I forgot to mention that if there's one thing, one little thing I like about Percy's work here is that he knows how to portray Emiko. She simply sounds right.
On the other hand (and this is actually a big problem), he doesn't know how to portray Oliver, Percy makes him take himself way too seriously and sound pretty stupid while he's at it.
Also, God, the guy has made me hate Fyff. During Lemire's run he was a bit of a dork but genuinely invested in helping others and being competent at his job. Here, he just doesn't care to the point that he almost let Ollie and Emiko get killed because he was taking a dump in the worst time possible.
Yep, there's an issue focusing on the supposed "mythology" around George (which could turn-out to be either really cool or really stupid).
Also, the villains got fortunately killed here. Unfortunately, their deaths were so abrupt that failed to leave an impression.
