He's not even that. He's so inconsistent that you never know what his motivations will be from one episode to the next (which could be considered terrible, I guess). Maybe there's some method to the madness and this shit is by design, but this definitely AIN'T Preacher. It feels more like a weird story with a Preacher skin on it. Or a fan-fic where the "fans" had only read the Cliffnotes.
I'm still watching out of pure morbid curiosity at this point (and my girl is interested). Admittedly, shit hasn't gotten so egregious that I throw my hands up and sceam "DONE!"
... yet.
