In “Task,” premiering Sunday on HBO, Brad Ingelsby, creator of the 2021 miniseries “Mare of Easttown,” which introduced the wider world to Wawa and the Delco accent, returns with another tale of crime and family in the rural-suburban wilds west of Philadelphia. Where women were at the center of “Mare,” men are the subject here — a cop and a criminal, symmetrically arranged — messed-up middle-aged single fathers who care about their kids.

Both have been loaded with tragedy. Robbie (Tom Pelphrey), whose wife took off a year before, has a much-missed dead brother in whose house he’s living with his two kids and young adult niece (Emilia Jones as Maeve, a secret hero); he’s a garbage collector with a sideline in robbing drug houses, which he identifies through their trash. This routine has been successful enough that he and his partner, fellow trashman Cliff (Raúl Castillo), have drawn the attention of the authorities.

FBI agent Tom (Mark Ruffalo) has a dead wife (Mireille Enos, seen briefly in flashback), a son in jail he can’t bring himself to visit and a semi-estranged adult daughter (Phoebe Fox); on leave from field work, he’s been manning the agency table at job fairs. That changes when his boss (Martha Plimpton), much to his displeasure, calls him back as a substitute to lead a task force into the drug house robberies, already assembled by his predecessor from other branches of law enforcement. There’s Lizzie (Alison Oliver), young and distractable; Aleah (Thuso Mbedu), terse and focused; and Anthony (Fabien Frankel), loose and Italian.

It’s clear from the guns that both sides pack, and the fact that Robbie has been stealing from criminals — notably a drug-dealing motorcycle gang, the Dark Hearts, which has its own explosive internal business — that something is going to go fatally wrong sooner or later. (If that’s a spoiler, you are blessed with a special brand of naivete.) The bikers, who are not at all nice, though painted with some recognizably human qualities — represented primarily by Jamie McShane as Perry and Sam Keeley as Jayson — are the usual screen collection of exclusively good-looking men and women, though to be fair, this is true of Tom’s team too — Tom perhaps excepted. (Ruffalo put on weight for the role, and wants you to notice.)

In “Task,” Robbie (Tom Pelphrey) is a single father who steals from other criminals.

Indeed, the predominant experience of watching “Task” is waiting for the next terrible thing to happen, which may be called suspense or dramatic tension, but in the event makes for an often depressing watch, especially since the safety (physical, psychological) of young children is involved. (That can feel a little cheap, dramaturgically, like endangering a kitten, but it works.) One is grateful for anything relatively ordinary — Lizzie and Anthony dancing in a bar, Tom’s younger daughter, Emily (Silvia Dionicio) connecting with a co-worker at the custard ice stand. (Another item for the regional reference bucket.)

In the compare-and-contrast structure of the series, we learn that Robbie, though he is a fount of bad decisions, is the more optimistic, proactive of the two characters — he has a dream, in the form of a brochure, regarding a Canadian island, where he would like to spirit his family away. (He’s doing the crime to afford it.) He’s interested enough in finding “a life companion” to open a dating app. Tom, who had been a priest for eight years before losing the spirit and joining the FBI, still in mourning for his wife, drinks too much, is packing a paunch and can’t connect with Emily, the only family member left in the house.

Both have connections to nature. Tom, who grows vegetables, is a birdwatcher; Robbie keeps chickens. Both are essentially tenderhearted, which is perhaps not the most practical quality for their professions, but necessary for the story — we need to like them. They’re like one and a half sides of the same coin.

In among the criminal antics and police work is a lot of talk about life and death and God, guilt and forgiveness. Ingelsby thinks big. The title to one episode, “Out Beyond Ideas of Wrongdoing and Rightdoing There Is a River,” paraphrases the 13th century Persian poet Rumi, and water is a motif — diving into it, swimming in it, hanging around by it. Birds, too, which show up in random shots and, like the lakes and rivers, function as a sort of psychic relief for the viewer and metaphors for the story. When Tom, speaking to Robbie, identifies a certain bird as a “vagrant … a bird that strayed outside its normal range, strayed so far that it’s forgotten how to find its way home,” that is not really about birds. The writing can be a little on the nose, but better a violent story with ideas than one with none.

For all my reservations when it comes to this sort of drama, it’s very well made and very well acted, and, where many crime stories settle for sensational nihilism, “Task” does want to leave you feeling … pretty good. Not horrible. Hopeful. I trust that hasn’t spoiled it for you.
