Greg Berlanti’s Love, Simon (B) is quietly revolutionary as a first mainstream teen coming of age movie featuring a gay protagonist, but the struggle with identity extends beyond its titular character to a somewhat milquetoast story and screenplay topped with a dollop of vanilla tone. The film is largely fun and occasionally quite moving, and its buoyant charm lies primarily on the shoulders of Nick Robinson, extremely likable and in almost every frame of the film as Simon. There’s a bit of mystery about the email pen pal at the center of the plot, but mostly the story centers on Simon and his group of friends coming to grips with teen romantic entanglements. Some characters are drawn too large and others underdeveloped in a movie that wants to be John Hughes-ian but rarely yields to its inner mania. It’s all a glorious first step for Hollywood movies but could have been made more memorable in the hands of a more creative filmmaker. Much like Philadelphia received some flack for sugarcoating its story in the first mainstream trailblazer to address the AIDS crisis, Berlanti’s film stays mostly in a safe lane to showcase coming out in the modern age. Expect the film to spark some changes of heart even as it clings to a pretty by the book formula.
