Dirty Grandpa (2016)

Dirty Grandpa is the kind of shameless, no-filter comedy that gets its charge from watching a buttoned-up young professional dragged—kicking, sweating, and occasionally half-naked—into a week of bad decisions and worse influences. Robert De Niro commits so hard to the foul-mouthed grandpa act that the movie becomes a dare: how far can a legend go when he decides dignity is overrated, and how much can Zac Efron’s tightly wound straight man take before he snaps? The vibe is raunchy, rowdy, and gleefully subversive, with Aubrey Plaza adding a mischievous spark that keeps the chaos from feeling one-note. It’s absolutely not for the easily offended (or anyone allergic to R-rated excess), but if you want a crude, high-energy laugh machine that occasionally surprises you with its oddly liberating spirit, this one delivers.

Dirty Grandpa is trying to be a raunchy, anything-goes road-trip comedy where a buttoned-up guy gets yanked into chaos by his unapologetically filthy grandfather. The problem is it leans so hard on shock value—nudity, drugs, mean-spirited gags, and “did they really just do that?” moments—that the actual joke-writing and story feel thin and repetitive. De Niro’s commitment and Zac Efron’s willingness to look ridiculous give it occasional energy, but the tone is all over the place and the movie often mistakes offensiveness for humor. If you like crude spring-break antics and don’t mind tasteless punchlines, you’ll probably coast through it; if you need cleverness, warmth, or even basic restraint, this will feel like a long night you can’t leave.
