Hi @jennarg many of the science fiction movies portray aliens as villains because of the frequent viewing of such fiction stories that makes us overthink and constantly ask about the existence of aliens. Marvel Studios is one of the producers that explores the alien theme in several of its films, such as the 'Guardians of the Galaxy'. The movie 'Eternal' is another example, and it cannot be denied that the film is interesting for most people, including myself.
