Profoundly stupid looking. I can think of several uses of Catholic clergy in comics that are more nuanced. One of the better ones was the use of a Catholic priest in an old DC title ‘Suicide Squad’ which was about a team of super-villians who are offered pardons and fresh starts by the government if they undertake hazardous missions for them. Their base had a priest as a chaplain and he was portrayed as a very likeable figure who was conflicted about the morality of the govt. programme. Catwoman’s sister was at one point a nun (although this may no longer be true as DC has rebooted their continuity as of late last year) and was at points portrayed sympathetically although she often clashed with her sister regarding religion. Later writers chose to have her leave her order and marry, which was actually handled surprisingly well for the most part.
Over at Marvel comics Nightcrawler of X-men fame was of course studying to be a priest and was ordained at one point. Although sadly Christ Claremont who introduced his faith as a part of his character plainly had more of a human and sympathetic understanding of various faiths than later writers who wrote this character.
Daredevil’s mother is a nun of course in the mainstream continuity and that was handled quite well also and her faith was portrayed as genuine and heartfelt. Those are superhero comics where we expect a certain level of the ridiculous as a genre convention but this graphic novel looks pretty poor based on that art work. I’d have to read it in fairness to see if my initial suspicions are borne out but it looks like the kind of silly versions of clergy you see in some anime.
