The first couple were compelling reading. The Alan Moore installment also looks interesting, but I haven't read it.
It's hard to say it's great, because it's ridiculously edgy, but the concept is uniquely horrifying. If you haven't read it, it's about a virus, rather like the zombie apocalypse viruses we have seen time and time again, and just like such a virus, it turns the infected into murderous monsters.
However, unlike mindless zombies, they retain their memories and abilities, but just immediately submit to their most evil impulses. So a nuclear power technician would pull out the control rods, an airline pilot would immediately crash into a building, etc. They have as little self-preservation as zombies, and their dangerousness is only limited by their lack of long-term planning.
The concept is brilliant. In actual practice, the evil is raperaperaperapeRAPEraperaperaperaperaperaperaperapeRAPERAPERAPE. And a bit of rape.
One major problem with the series is the uninfected are themselves utterly repellent and unsympathetic, and it becomes difficult to care much about them. To an extent, this occurs in any apocalypse story, but it's at an extreme here. For instance, in one of these, our "heroes" cold-bloodedly murder an entire school full of children because reasons. It's pretty hard to sympathize with these characters at that point.
My favorite character is called Horsecock. He's called that because he beats the shit out of people with a severed horse cock while yelling "HORSECOCK!" This is a high-functioning Crossed.
Anyway it's well worth a look but YMMV on whether you can even stand it at all and/or whether your interest rapidly fades after two or three installments.
