“Short, Not Sweet,” a collection of five sardonic short films. Included: Two Young men woo young women in exactly the same way in “The Fine Line Between Cute and Creepy”; “La Puppe” follows a reckless pooch (actually a toy dog) using only still photos; a second-grade class suffers a run of bad luck in “The School”; the animated “A Monster's Calling” explores personal anxieties; and “Why the Anderson Children Didn't Come to Dinner” follows a macabre family through three meals.
