I kind of enjoyed Alien: Romulus. It’s a solid, workmanlike ‘haunted house in space’ movie — creepy, scary, and, unfortunately, familiar. If you like Alien, you’ll like Alien: Romulus because at it’s heart it’s exactly the same movie with different set dressing.
I had the leisure to think about what I was seeing, since the plot wasn’t much of a distraction, and I found myself wondering about the biology of the xenomorphs. There’s a lot of silliness there. One small thing I noticed was how slow and awkward the xenomorphs are. No real predator would stop and vogue in front of its prey, slowly opening its jaws to extend a second set of jaws while hissing and dripping. It’s become an indispensable trope in these movies, and sure, it’s intended to slowly ramp up the tension, but that’s not how predators act.
I feed spiders twice a week. Here’s how they act: they take their time prepping. They go on alert when something stumbles into their web, orienting themselves and rising up on their legs and paying close attention. That could be a terrifying moment in the scary movie, with that moment of tension, but when it is time to attack, they don’t delay — they move fast. They dart forward, immobilize the prey with more silk or a swift bite. They don’t stupidly pose prior to trying to disable the big creature they want to eat.
Maybe you’re not acquainted with spiders. I’ve also been attacked by a dog. It did not run up to my leg, stop, cock its head, snarl, and then slowly try to bite my calf (try, because I pedaled my bike and got away). If you’re making your living by killing your food, you don’t make it a cinematic experience, you get the business over with as quickly as possible.
Another thing that bugged me was all the slime. I don’t object to wet puppets, but the action is all taking place on a big metal ship. Where is all that water dripping off these aliens coming from? Wouldn’t a ship be equipped with dehumidifiers to extract all that water out of the environment? I know there were several scenes with partially flooded chambers, but why? I’m sure condensation is an issue in a ship, but in the future, ships in the vacuum of space don’t need to conserve air and water? How nice for them.
I’m not going to try to address the energetic cost of synthesizing and containing a highly reactive substance in their blood that has the ability dissolve its way through multiple levels of a metal spaceship.
