The advance hype for “Don’t Worry Darling” has been so incessant – from director Olivia Wilde’s location-turned-relationship with her leading man, Harry Styles, to a Kabuki-like feud with her lead actress, Florence Pugh, and something involving Chris Pine and Styles at the recent Venice Film Festival – that it’s easy to forget there’s an actual movie at the center of it all. A movie that’s not a disaster, but not particularly distinguished; a movie that, in the end, will wind up being as forgettable as its own bizarre publicity.
