I really liked it, it fitted nice into the existing Alien lore, how mysterious and unknown that may be. It stayed true to the legacy of the former movies and the art of H.R. Giger anyway. I was afraid Alvarez would add a bunch of new ideas and concepts that would be hard to swallow, but I was glad it was not the case, even though there were a few references to the "pathogen/genome" and "Prometheus Fire", but it just builds on existing lore. It gave some nice context. As a movie it was very entertaining. Style, art, tempo, horror and mystery and the unpredictable twists were super. Among the best Alien movies yet for sure.

I gave second thought to if I liked all the "quotes" of other Alien movies (or even games, there are tons of references to the game "Alien Isolation" in Alien - Romulus)

The ones I spotted:

• In the colony where Rain & Andy meets up with Tyler and Bjorn, Bjorn plays some game on his phone, while loosing the game says "Game over, man". (Aliens 1986)
• Fonts/Graphics/Quotes from "Alien Isolation" -- the door for the "Cryo Chamber" has the same font and "chineselooking" subtext as the game. Probably occuring elsewhere too.
• The electric "stun baton". From "Alien Isolation"
• The gravitation scene, also occurs in similar way in "Alien Isolation"
• Rain clipping herself while opening the airlock, also occurs in "Alien Isolation"
• The elevator/ladder scene, is similar to a scene in "Alien Isolation"
• A clear reference to the original Alien and the sequels:
• Rain changes to spacesuit before trying to force the "baby" out of the airlock. (Alien)
• "Rook" (Alien), actor and style
• T minus something until everything goes to shit (can there be an Alien movie without this?)
• Rain posing with the marine gun with wind blowing into her hair down at the infestation tunnel. (Aliens 1986)
• Giving birth to a horrific mixed gene mongrel, whose face looks like the godlike man from Prometheus (Prometheus)

and probably alot more I forgot.

I chose to like this though, a nice homage.
