This ending was truly disappointing and so weird. I'm not sure if I understood what happened, but either way I was left with some unanswered questions. It was a good series overall, but it had the potential to be even better. I really enjoyed volumes 2 and 4 (the Hollywood film industry in the 50s and rock-n-roll in the 90s environment were on point). After reading volume 4 I really expected a mindblowing finale but I didn't get that. The art was overall ok. Some of the drawings (few fortunately) were a bit sloppy. However, I care more about the storytelling so that didn't bother me much. 
 Still, I would recommend these graphic novels for noir enthusiastics.
