The title of “A.C.O.D.” stands for “Adult Children of Divorce,” apparently a subject director/co-writer Stu Zicherman knows all too well. He also, thankfully, has enough distance on it to keep his movie lightly knowing and occasionally laugh-out-loud funny while acknowledging the real pain a grown man (Adam Scott of TV’s “Parks and Recreation”) can experience when dealing with parents who act like squabbling children.
The hero has to get his long-divorced mom and dad (Richard Jenkins and Catherine O’Hara) to both show up for his brother’s wedding, and the experience brings up all the old traumas. The movie’s messy, predictable, occasionally sitcom-shallow, but it’s blessed with a cast of pro farceurs—including Amy Poehler and Jane Lynch—who put a spin on almost everything they do.
