In “Almost Christmas,” Danny Glover plays Walter, a recent widower who spends a lot of time in the kitchen, trying over and over again to replicate his late wife’s legendary sweet potato pie. What he wants to replicate, of course, is the time when his family was all together, as shown in a heart-tugging, gracefully edited opening credit sequence, with the years melting into each other from 1971 to 2015. A young couple embraces on a mattress on the floor and, as it happens in life, an eye blink later they have three children, and then, as a bit of a late surprise, a fourth. The children are all adults now, coming home for the first Christmas since their mother died, and Walter wants it to be a time of reconnection. For that, he needs the sweet potato pie and it has to be just like hers.

Writer/director David Talbert (“Baggage Claim”) is trying for his own version of a sweet potato pie with this film, mixing in the standard ingredients for a Christmas family gathering comedy/drama movie. So, there are adult siblings with ongoing conflicts, a dad who is spending too much time on work, precocious kids (in this case, happily uploading every element of family dysfunction on social media), church, a guest star (though why you would put Gladys Knight in a film and not let her sing is beyond me), family traditions, a kitchen disaster, secrets to be revealed, a rekindled romance, a busted marriage, high maintenance in-laws, and, of course Christmas meaning and reconciliation magic and a lot of food. In other words, other than running into Gladys Knight, it is pretty much what goes on around the world at Christmas.

Talbert’s sweet potato pie of a movie has the right ingredients, and if they are not always combined just right, it still makes for a treat, with an exceptional cast and enough laughs to keep us going until the exact right moment for some tears.

Walter’s older son is Christian (Romany Malco), a husband and father of two who is running for Congress (none of this storyline makes any sense as Christmas is at least 11 months before the next election and the issue he gets caught up in is municipal, not federal, but okay). Malco is terrific in an unusually understated role. The look on his face as Walter asks him to speak at the homeless shelter his mother was devoted to shows endless tenderness and loss. His wife (an underused Nicole Ari Parker) is mostly there to remind him that he should not take time away from the family for his campaign. The youngest of Walter’s children is Evan (Jessie T. Usher), a college football player being scouted for the NFL draft, hiding an addiction to painkillers.

Their two sisters are Rachel (co-producer Gabrielle Union), a fiercely independent single mom and law student, and Cheryl (Kimberly Elise), a dentist married to a know-it-all former basketball player (J.B. Smoove), who is still a player, if you know what I mean.

Walter’s outspoken sister-in-law, a backup singer named May (Mo’Nique) arrives to wear a wild assortment of wigs and prepare an even wilder assortment of exotic foods that no one will touch. Rachel’s high school friend (Omar Epps) would like to renew their acquaintance. And Jasmine (Keri Hilson), Christian’s campaign manager (John Michael Higgins) and Evan’s friend (D.C. Young Fly) show up for various complications.

Like Walter’s pie, it’s not quite as good as the real thing. It would fit it well with Hallmark’s line-up of non-stop Christmas movies from Halloween through New Year’s Day. But there’s a reason those movies are so popular. They remind us of our own chaotic but still memorable holidays and our own difficult but still wonderful families.

Parents should know that this film includes some sexual references and a non-explicit situation, prescription drug abuse, sad offscreen death of a parent, offscreen car crash with injuries, gun, and some strong and explicit language.
