One of the unexpected joys of the movies so far this year has been Love, Simon, Greg Berlanti’s touching and heartfelt adaptation of Becky Albertalli’s bestselling YA novel, Simon Vs The Homo Sapiens Agenda. The first mainstream teen rom-com with an LGBT character at its core, the film took huge pleasure in wholeheartedly engaging with the standard tropes of the romantic comedy genre, rather than expending much of its energy or charm in trying to subvert them.
