Three years in the making, this new film from acclaimed documentary filmmakers Joe Berlinger and Bruce Sinofsky (the team that created "Brother's Keeper" and "Paradise Lost") provides a fascinating, in-depth portrait of the most successful heavy metal band of all time, as they faced monumental personal and professional challenges while recording their first studio album of original songs in five years. In the tradition of such seminal music documentaries as "Don't Look Back" and "Gimme Shelter," "Metallica: Some Kind of Monster" seeks to transcend the conventions of the "rock 'n' roll movie" genre, trading rock-star posing for truthful introspection, and revealing an intimate portrait of the individuals behind a legendary band and their unique creative journey. Highly recomended.
