Alien movies have continued to be produced into the present-day, including the mind-numbingly campy Alien vs. Predator (2004), and Aliens vs. Predator: Requiem (2007), and two disappointing and overly complex prequels directed by Ridley Scott: Prometheus (2012) and Alien Covenant (2017). Both are excessively reliant upon massive computer animations and odd conspiracy theories related to ancient human civilizations. As with most Hollywood classics, this series has sadly been beaten into the ground from a once brilliant film. Lamentably like many other once successful franchises Alien has devolved into a cheap, unoriginal, cash-grabbing string of sequels. It is our great misfortune that more sequels are likely to come.

Ranking My Favorite Alien Films

#1 Alien (1979)

#2 Aliens (1986)

#3 Alien III (1992)

#4 Alien Resurrection (1997)

The prequels and the Alien vs. Predator movies are a waste of time in my view.
