While not always the darling of critics, the musical “Beetlejuice” has found a solid fan base among gen Z who, as many articles have noted, have been prominent audience members of since its Broadway premiere and throughout its touring performances. Many show up in costumes reflecting some of the story’s main characters à la cosplay. Some come as the teenager Lydia decked out in black frill, while others come in the black and white stripes like the main ghost of the show.
