a list has been compiled of the worst movies, with some outlets focusing on specific genres such as sci-fi, action, and superhero films, as well as particular time periods like the 1990s and 2000s. some of these lists include movies that are ranked as 0/10, implying they are considered to be of very poor quality. the lists appear to cover a range of film categories, but it is unclear if they all draw from the same overall list of the 10 worst movies.
