Ruth Negga and Himesh Patel also star in the Netflix original, with ‘Schitt’s Creek’ co-creator Levy as an artist who spends a year mourning his husband before making a startling discovery about their relationship.

The London and Paris locations are pretty, the likable cast all look stylish in their voluminous coats and slouchy pants and distressed knits, and the countless teary-eyed close-ups are designed to touch our hearts. But Netflix’s Good Grief, despite its characters’ extensive soul-dredging, is all surface, perfectly watchable but a little dull. Working both behind and in front of the camera after having cut his teeth directing episodes of Schitt’s Creek, Daniel Levy has made a first feature that’s a glossy drama of love and loss and the restorative power of friendship. But it’s more earnest than affecting.

Before he heads off to a book signing in Paris, Oliver oversees the annual singalong segment of their holiday party, leading the guests in a gorgeous choral arrangement of William Bell’s seasonal classic, “Everyday Will Be Like a Holiday.” It’s the most emotional moment in the movie. But Marc has barely said goodbye when flashing lights from the street outside reveal an accident involving Oliver’s taxi.

Marc’s unsettling discovery from the couple’s accountant (Celia Imrie) that Oliver owned a pied-à-terre in Paris leads him finally to open the Christmas card his husband handed him before leaving that fateful night. What he learns forces him to rethink his entire marriage and seems to make a mockery of the year he has spent grieving. Keeping the information to himself, he invites Sophie and Thomas to spend a weekend with him in the French capital, ostensibly as a thank-you for their loving support.

Similar situations in which widowed spouses find themselves confronted by their late partners’ secrets have been explored in films ranging from Euro auteur drama like Kieslowski’s Three Colors: Blue to forgettable studio efforts like Sydney Pollack’s Random Hearts.

But Levy’s interest in that eye-opening discovery goes only so far. Eventually, external factors leave Marc no choice but to fill in the missing details for Sophie and Thomas, by which time the focus has shifted to the emotional stagnation in the lives of all three. Their mutual dissatisfaction bubbles up while riding the giant Ferris wheel at Place de la Concorde, set against the backdrop of Paris’ twinkling night sky.

The shimmering melancholy of Rob Simonsen’s score is often left to suggest a depth of feeling that’s missing in the writing and, by extension, the performances. The script is sensitive but never terribly probing, and the movie’s intimacy more staged than lived-in. Having Sophie put Neil Young’s “Only Love Can Break Your Heart” on the turntable while raising a glass “to the fucking pain!” is just too on the nose to be anything but mawkish.

Like Dever’s ill-fitting cameo, Emma Corrin turns up for a thankless moment as a performance artist flailing about in a web of knitting in a London warehouse gallery space. But aside from showing the three friends in their artsy milieu, the scene adds nothing.

Maybe there’s something to be contemplated here about grief as a pathway to self-examination and creative rebirth. There’s certainly no reason to question the sincerity of Levy’s intentions. But he hasn’t managed to flesh out all the emo talk into compelling drama, making a film that’s passable as streaming fodder (it hits Netflix Jan. 5, after a week in select theaters), though not sufficiently distinctive to draw you in and make you care much about its characters.
