The Take
Dirty Grandpa is raunch for raunch's sake, a 106-minute parade of sexual degeneracy and crude gags that treats vulgarity as the only punchline. Robert De Niro and Zac Efron commit hard to the bit, yet the script never builds characters or stakes beyond the next nudity joke.
The film markets moral vacuum as edgy comedy and delivers exactly that: no thesis, no growth, just ancestors filing restraining orders while the audience loses brain cells.
The Verdict
Dirty Grandpa exists only to cash in on star power and lowbrow shock value. It offers no story worth following and no laughs that survive the next morning.
Skip it.
