“Good Grief” is Dan Levy’s delicate and arms-length drift through the psychology of mourning, with that grief complicated by post mortem secrets that emerge about the deceased.

It’s a featherweight attempt at the gutting, deflated feeling of loss, with clever characters in a tony setting — London’s arts and entertainment scene — and sometimes amusing put-downs but few serious insights into the human condition.

Levy’s feature writing/directing/starring debut is more glib than great, but it’s pleasant enough if never quite as poignant as he’s shooting for.

The “Schitt’s Creek” alumnus plays Marc, a North American living in London with his Young Adult Fiction-writing husband, Oliver (Luke Evans).

Marc is reserved, devoted, detail-oriented in planning their lavish Christmas party, complete with a jazz combo. Oliver is gregarious, the life of the party, leading one and all in a lush, choral version of William Bell’s “Every Day With be like a Holiday” that he arranged.

They exhange banter with their besties — Thomas (Himesh Patel of “Yesterday”) and the spirited, tipsy, sings-too-loud costume designer Sophie (Ruth Negga as we’ve never seen her).

“Your voice is like a church organ someone threw out a window” won’t shut her up.

Then Oliver kisses his husband goodbye with a “We have lots to discuss,” gets into a cab and never makes it to his Paris reading and book-signing. Marc will spend the next year trying to recover from “the time I watched my husband get pried out a cab, like escargot.”

There was a Christmas card Oliver left behind, which Marc finally reads and doesn’t share with anyone. It dryly announced “I have met someone outside of us.”

Marc is left to deal with a funeral, financial fallout from a writer in a long-term (novel series) contract, and a secret — which includes a pied-à-terre in Paris that only Oliver’s death revealed.

Marc must gather Sophie and Thomas for a trip to check this place out, with him hunting for answers and closure, and them not having a clue about this new wrinkle in their quiet, painter-who-can’t-paint friend’s grief.

Levy’s chief gifts are as a writer and performer of dry, acidic one-liners, and he gives himself and his co-stars a few of those, if never quite enough to make this sad story comical.

“She wears ‘logic’ like one of those little handbags that can’t actually hold anything.”

The character arcs here aren’t broad or decisive, just a man coming to grips with having “lost a year of my life” to something that wasn’t what he thought it was. “Growth” is ladled onto Sophie and Thomas, but only perfunctorily.

Levy writes himself a melancholy drunken karaoke scene, a mild-mannered (he is Canadian, remember) restaurant blow-up and a couple of muted confrontations that aren’t as satisfying as one might hope. He’s yet to show us much range, and he’s written himself a more introverted version of characters he’s already played.

But “Good Grief” is sober-minded, considered and almost sweet. Compared to other Netflix deals with writer-directors given a big check to film their indulgent “dream” project, it’s also modest and sometimes compelling.

Fair enough, but let’s see what he manages the next time he’s given this opportunity.
