Hmm this is concerning, has anyone notices how the Original Alien is treated like Artsy Thriller and Aliens is a pulp Action film and the subsequent movies would reflect this to a degree.
Alien 3, AVP and Promethues for all their strengths and weakness pursued being of some substance and profound concept.
Wheras Alien Resurrection, AVP R and Alien Covenant fall more into schlocky pulp Action, and that after each film there's a far absence of Alien films for a while. Maybe that's just one way of reading it.
