In the delightful new road trip comedy, “Monuments,” a young widower navigates his way through grief, loss, and family chaos by taking his late wife’s ashes and embarking on a spontaneous journey across America’s heartland. Ted, played by David Sullivan, meets a variety of quirky individuals, including his adversary Howl, portrayed by Javier Muñoz, who both help and hinder his quest to rediscover something he lost long before his wife Laura, played by Marguerite Moreau, passed away. “Monuments” blends humor and optimism into a narrative about mourning, loss, and marriage, making it one of the most uplifting indie films of 2021.
