There are some moderately serious issues with Alien: Romulus (we all like the seven-foot-tall Alien, but a Chestburster can't turn into one after ten minutes, it's not Ant-Man), but on the other hand, I've been so down on franchise films like Bond and Spider-Man for not willing to be "just another Spider-Man adventure" that I'm kinda grateful this is just a grounded movie about a handful of characters trying to survive the Alien.
There's no multiverse, it's largely the classic alien instead of a bunch of weird experiments with no rules, they don't even fight the Predator. There's a lack of pretense and a skill at making Just A Cheeseburger that reminds me of the Godzilla/Kong movies. Lizzard. Monke. Why overthink it?
