Alien: Romulus was... a mixed bag.
I
loved the first 40-ish minutes or so. It was so fucking immersive and textured. Pulled in immediately when they were still in the mining colony and making plans and you could hear all this industrial machinery going on in the background. It felt so damn grimey and sordid and dark and hopeless long before we got to the alien shit. Then we get to the space station and it plays up the industrial horror of humans exploring an abandoned, automated sci-fi facility completely indifferent to their existence. It gets so much mileage out of the hostile environment long before the xenomorphs enter the picture. Then we get the inevitable facehugger introduction and it falls apart into a jumbled mess of jumpscares and loud noises. All the subtlety and atmosphere of the first act just gone.
It recovered somewhat with the elevator shaft setpiece and if that had been the climax I'd have been happy. Unfortunately it kept going and let me tell you, a lot of people in my theater could not contain their laughter when they introduced the
and I can't exactly blame them. Somehow I don't think that's the reaction you want out of the climax of your Alien film.
Lastly, the cast was fucking awful outside of the main girl and the two androids.
So all in all... it was about 50% "genuinely great" and 50% "laughably bad", with very little in-between.
