Louis C.K. loves a mess, and I Love You, Daddy, his first feature film as a director since 2001’s Pootie Tang, is exactly that. That’s not to say that each and every scene lacks purpose, but that chaos, mostly of the emotional sort, is C.K.’s preferred m.o. He’s certainly treading into hot-button territory throughout this often funny yet ultimately flimsy dark comedy about a flavor-of-the-month sitcom writer, Glen Topher (C.K.), whose spoiled 17-year-old daughter, China (Chloë Grace Moretz), takes up with 68-year-old Leslie Goodwin (John Malkovich), a film director who Glen worships, and also a known lech who’s equal parts Roman Polanski and Woody Allen.
