“Grandma” opens Friday at Sundance Cinemas. R, 1:22, three stars out of four.
“Time passes. That’s for sure.” The epigram from poet Eileen Myles opens writer-director Paul Weitz’s comic drama “Grandma,” and the film doesn’t get much more profound than that in exploring its themes of aging and regret. But Weitz (“About A Boy”) isn’t aiming for sweeping profundity, instead making a character study that’s small, sour and sweet — like one of those hard candies your grandma had in a bowl by the front door.
