The core pitch becomes quite formulaic. It's a fun kind of formulaic, but all the SCPs are made from the same relatively small set of moving parts, painted with different colours and textures for each specific monster.
But as a concept it's still one of the freshest things to appear in SF this century, and it's a wonderful contrast to more standard action hero SF.
Right. I respect it for what it is, and there are elements that are amazing and deeply thought out. But there's an alternate universe where the whole of it is a big cohesive vision statement in the metaphysical/visionary subgenre of Scifi a la Blindsight by Peter Watts or Annihilation by Jeff VanderMeer. But has that potential but where it lands is closer to monster-of-the-week in book form.
