The A.V. Club
The would-be comic conceit of a foul-mouthed old person is, at this point, only slightly younger than the ability to depict foul-mouthed characters in cinema. The fact that anyone would consider this sort of character a shocking yet hilarious delight is almost inherently anti-comedic; it’s hard to laugh from inside the deep depression caused by smug faux-edginess. Yet having acting legend Robert De Niro play a recently widowed and extremely foul-mouthed senior citizen—basically the Johnny Knoxville role in Bad Grandpa minus the prosthetics and performance art—is not necessarily the automatic travesty some would suggest.
