A movie about childbirth, pregnancy and fatherhood? Though those three elements combined seem like a recipe for disaster for a Hollywood film, “Delivery Man” makes them work together fluidly in its tale of a delivery truck driver who has fathered 533 children as a result of a sperm donation decades before.

Vince Vaughn headlines the film as David Wozniak, the “delivery man” whose life is in shambles—a loan shark is hunting him down, his pregnant girlfriend refuses to talk to him and his family has labeled him a failure. On top of all of this, the clinic David donated his sperm to gave only his sperm out to every client for a two-year period, and now 124 of his biological children have banded together to file a class-action suit to discover their father’s true identity.

The premise of “Delivery Man” is clever and funny, though not nearly humorous enough to be labeled a comedy. As David gets to know his now grown, young-adult children, from aspiring actor Josh to multiple sclerosis-suffering Ryan, one can’t help but feel the movie tug at their heartstrings. While the character of Viggo, played by Adam Chanler-Berat, provides numerous gags throughout the duration of the film, the movie falls short as far as downright comedies go, providing more of a romantic comedy-type feel.

The best parts of the movie deal with the kids, resulting from David’s sperm donations. All of the actors portraying David’s children are lively, and the weekend outing organized by the children who planned the class-action suit turns out to be one of the best scenes in the entire film.

However, the movie could’ve fleshed out more of the relationships David has with his children, rather than spending time dealing with all-too-familiar sub-plots. Who cares about David’s father’s disappointment in him, or how David needs to pay off his ridiculous loans? These minor details detract from the central plot, and are just downright predictable and boring.

While the movie presents a feel-good message, it neglects to provide the audience an ending. What happens after all is set and done? Does David keep in contact with his children? Does he attend all of their birthday parties, graduation ceremonies and weddings? Even after the movie ends and the credits roll, there are still a million possibilities of what could happen to David and his family.

Despite its overly-used subplots and unbalanced character development, “Delivery Man” is a heartwarming movie, with a sweet combination of tenderness and humor, and teaches everyone to cherish our loved ones and to give them a great, big hug.
