A.C.O.D. opens Friday at Sundance Cinemas. R, 1:27, three stars out of four.
“A.C.O.D.” is a movie that might properly described as “sitcommy,” although that speaks less to problems with the movie than just how good sitcoms are these days. With sharp writing and acting, including two of the stars of “Parks and Recreation,” “A.C.O.D.” (“Adult Child of Divorce”) is in the tradition of everything from “I Love Lucy” to “Modern Family,” an amusing collision between insufferable people and those who try to suffer them. It’s more a situation than a story, but a pretty funny situation.
