I love musicals. I grew up watching Chitty Chitty Bang Bang. I was obsessed with Sweeney Todd at school. I love Hamilton and am even partial to a bit of Russell Crowe in Les Miserables. But some of the worst films are musicals – and video-game adaptations, but let’s not go there! Pitch Perfect 3 or Cats are beyond help, but the film that disappointed me most was The Greatest Showman.
