In the comedy film A.C.O.D. (Adult Children of Divorce), Carter (Adam Scott), a seemingly stable restaurant owner, finds his peace of mind and comfortable life dissolving when his younger brother (Clark Duke) gets engaged. Tasked with getting their still-battling divorced parents to attend the event, Carter finds their drama soon envelopes his life, too. While the filmmakers perfectly capture the pettiness, bitterness, and spitefulness of divorce, they provide a one-joke movie that's short on laughs, despite a delightful cast of comic actors. Deception, Infidelity, Immaturity Richard Jenkins and Catherine O'Hara play the warring parents, still spewing venom and refusing to see each other after 15 years of divorce. Both remarried, (to characters portrayed by Amy Poehler and Ken Howard, respectively), they lie, scream, and indulge in other childish behavior as Carter tries to make peace for his younger brother's sake. Compounding this stress is Lauren (Mary Elizabeth Winstead), Carter's girlfriend of four years who indicates (truth in jest) she's getting a little tired of waiting for his commitment. Based on what we learn of his past, it's no wonder Carter chooses to remain single. Threatening to crack from the pressure, he revisits his childhood therapist, Dr. Judith (Jane Lynch), and learns she was never really his therapist, but a book researcher documenting the devastating effects of divorce on children. He reads the book and sees himself through someone else's eyes, a shocking realization that escalates his problems. Cue the wacky comedy background music.
