About My Father is clearly intended to be a cringe comedy a la Meet the Parents (it even features Robert De Niro as another grumpy dad), but it stretches the concept of “funny” so thin that the memory of that scene in which a cat pees on the contents of a smashed urn will feel like dizzying comic heights in comparison. The premise — an Italian-American man struggles to win the acceptance of his WASPish in-laws — might have made sense 100 years ago, but today, it strikes as farfetched. Even without that weak foundation, much of About My Father has a shaky grasp on what makes a movie work. The screenplay feels like the product of crudely stitching together several over-manufactured set-pieces, with the result being an almost total lack of fluidity and characters who often contradict themselves.

The film starts out on its worst foot: star–co-writer Sebastian Maniscalco lays the voiceover on thick, while Sebastian’s brash Sicilian father Salvo (De Niro) is so unceasingly negative that it turns a presence that should be great into one that’s only grating. Though it does find something of a footing as a saccharine family drama in its back half, it’s much too little, too late.
