I don't remember where I stopped, not because it was so long ago but because I got lost reading it and ended up reading the same few chapters 10 times in a row before giving up like I tend to do in novels. Sure, it's technically amazing, but the busyness of the story and the claustrophobic panels just don't conduce for a good reading experience no matter how impressive it is. Maybe if I didn't have problems reading it I would have given it a much higher score, but I'm not revisiting any time soon.
Not the best for me, but not the worst.
