Gremlins is one of the few movies that can fall into multiple categories in terms of film genres, as it blurs the lines between horror and holiday. The film's plot revolves around a boy named Billy Peltzer, who's gifted a rare creature called a mogwai from his father on Christmas. Billy names his mogwai Gizmo, and while Gizmo is adorable at first, his dark side becomes apparent when Billy neglects to take care of him properly. Filled with Christmas imagery — including some hilarious caroling gremlins — Gremlins is the best of both worlds.
