Liza Minnelli and Halston in 1984 Credit: Rex It is a truism – and a joke from the Sex and the City 2 – that whenever there is a peak of gay energy in any room, Liza Minnelli automatically appears. I didn’t care for Sex and the City and its grasping archetype hags – it was consumerist Feminism, empty Feminism - but it is right in this sense, if only by coincidence or mistake. Minnelli is in Halston from Netflix, a new five-part series about the most original designer America ever produced, with the ever-watchable Ewan McGregor as her best friend Roy (Halston) Frowick. The show isn’t as creative as the man it is named for: how could it be? Netflix is gaudy and well-funded, but it is not imaginative, as its subjects were.
