Johnny Ryan returns with a quaint, subtle, and endearing comic about a police officer looking out for his community. There's rampant corruption in his precinct along with a potential predator ring operating out of a Trader Joe's basement, so naturally a well-meaning cop is the only one fit to save the day.
Obviously this isn't quite that, since Fat Cop is pretty much as vile and grotesque and outrageous as you'd expect from a Johnny Ryan joint. It's bountiful in the application of crass humor, particularly with related to toilet/bodily function type jokes. And of course, body mutilation, rape, and murder are par for the course here too. If Ryan's previous output hasn't done it for you, this one won't either.
The sheer slapstick nature of Fat Cop does allow for some decent satire of American culture, particularly with respect to contemporary policing. Ryan's madcap approach lays bare the critique though I wouldn't say there's anything too novel about the discourse here. A lot of the satirical slant comes from the depiction of the titular character, Fat Cop, who is a repulsive, gluttonous and violent individual that seeks the easy path towards getting his arrests but also revels in the power imbalance afforded to him by his station. Things begin to look down for him when he's assigned a new partner who begins to hold him accountable, though it's quickly clear that this new partner is terrible in his own kind of way. The story has a frenetic pacing to it, but the culmination of it involves a thinly-veiled reference to the "Pizzagate" conspiracy theory whereby a child sex trafficking ring is found at a local Trader Joe's.
Your tolerance towards crass humor is probably the barometer to be used when deciding whether or not this is for you. Ryan's longer works do struggle from the fact that he has to drag out a singular ridiculous premise for the duration of a graphic novel, and that is definitely felt here to a certain extent. But the visual gags here are a step up from Ryan's previous output, and I'd even argue that there is a semblance of more nuance here - difficult though it maybe to spot amidst the garish and juvenile artwork. Perhaps what I like more about this one compared to some of his other comics is that it feels more in line with typically genre piece and has a generally well-designed narrative structure. Sure, the jokes do get stale towards the end, but Fat Cop boasts sufficient variety in its application of crass jokes to sustain the page count well enough. Not necessarily one of his better comics, but it's entertaining nonetheless. Though how entertaining it is entirely subject to your taste with respect to this type of humor.
