'The Death & Life of John F. Donovan' is a mess - even if it's an intriguing one. The English-language debut of Canadian director Xavier Dolan ambitiously tackles themes of fame, privacy, sexuality, growing up, and, of course, mothers and sons but never really digs too deep beneath the surface of the very complicated issues it takes on. And from Green Day's 'Jesus of Suburbia' to Florence + The Machine's 'Stand by Me' and Lifehouse's 'Hanging by a Moment,' Dolan is at his worst when he allows his cringe-worthy choice of music to substitute for a deeper effort to underline his characters' emotional states. Still, at the very least, 'The Death & Life of John F. Donovan' is never boring with the big brassy performances from the movie's generally strong casts.
