Those Alien prequels (well, one prequel and one "not prequel") almost ruined the Xenomorph concept for me. I hate David having "created" them and the Space Jockeys being big blue humans so much (both concepts take away any mystery surrounding the Xenomorphs). Only when I say to myself Prometheus and Covenant happened in a separate universe and therefore don't count as canon (in my mind at least) can I watch the original movies in peace.
