As World of Reel reports, the film was screened for filmmakers and critics at the Directors Guild of America, where it received thunderous applause. Martin Scorsese was particularly vocal in his praise, calling Paul Thomas Anderson's creation "gripping and extraordinarily constructed." According to journalists, the master filmmaker wanted to support his colleague and strengthen his position in the awards race, especially since the acclaimed director still doesn't have an Oscar.
