Comedic Soul-Searching, Punctuated by Pyrotechnics Kevin Hart's new stand-up comedy film begins with a funny few minutes of self-deprecation as, in a staged bit, acquaintances casually refer to the more ignominious parts of his résumé: a loud divorce, a terrible movie ("Soul Plane"), some unflattering appearances in the celebrity press. But that is a red herring. Bombast and self-aggrandizement soon take over. The film, after all, is called "Kevin Hart: Let Me Explain," not "Kevin Hart: Let Me Apologize." The introductory segment eventually morphs into a swaggering travelogue full of clips from Mr. Hart's world tour, eventually landing him at Madison Square Garden and the heart of the film: a raucous stand-up set there. The Garden material is heavy on caustic references related to his divorce and love life, and light on the warmer-and-fuzzier Hart, whose gentle observational humor about being a parent suggests Bill Cosby with a somewhat fouler mouth. The phrase "liar, liar, pants on fire" may come to mind watching the film: Mr. Hart does a long bit about being a chronic liar and also has fun with onstage fire effects more common in a rock show. His fans will love it; their main complaint may be that it ends too soon. Amateur psychologists in the audience, meanwhile, may be asking why such a successful guy seems so defensive. "Kevin Hart: Let Me Explain" is rated R (Under 17 requires accompanying parent or adult guardian) for endless profanity and a drug reference.
