There really wasn't much new info in this voyeuristic piece of journalism that wasn't already known about Karl Lagerfeld - at least not enough to warrant a 90 minute film. His entourage of former friends and current employees at the time of his death didn't have a lot to say. The brief overview of Karl's childhood and early career, his rivalry with Yves St. Laurent, and his odd, sexless love life has already been written about ad nauseam. There was no investigation of his relationship with Chanel (they over-ruled his final request for a private funeral), and few interviews or private gossip spilled from former friends who had been shut out.
Karl had difficulty trusting people; he rewarded devotion with generous gifts and abruptly cut off anyone he perceived as disloyal. He was talented and driven, but also vain, privileged, secretive, and opinionated. In the end, he could really only share his unguarded love with a cat he called Choupette. The only mystery remaining is exactly when his personal fortune will be divided amongst the cat and a handful of heirs.
