"These days, otherworldly characters appear in a wide range of roles, from the alien force that mutates biological creatures in "Annihilation" to the more kindly, time-bending heptapods of "Arrival." With the wide number of alien movies throughout the history of film, how can viewers determine which extraterrestrial features are most worth their time?
To answer that question, Stacker compiled data (as of Sept. 2, 2020) on all sci-fi movies on Letterboxd, the film-based social media network, and selected the top 50 alien movies, ranked according to their average Letterboxd score. To qualify, aliens had to be main characters or central to the plot of the film."
