Everything that can go wrong in a space movie about life from Mars or other planets did go wrong in Life. The producers and writers didn’t defy any tropes with this one.
Life is truly true to its Hollywood film type/genre. Not to say that there is no hostile life the universe. Only that why does every life form that potentially exists in the universe other than human life have to be portrayed as completely hostile or completely docile?
It isn’t like white Europeans have a great track record with people from other nations, including their own. So I guess, as a film drenched in white ideologies, that it stands to reason that their enmity towards “the other” on Earth is reflected in their ideas about and portrayals of other life in the universe. Everything that is not them is a threat or it simply excites them to perceive the other as a threat and that’s the Hollywood selling point.
Your imaginations are pitiful.
