Theysit in Horror / Science Fiction territory. If that's the register that drew you to Them!, the second film will land in a comparable space — through a different lens.

London fog rolling in autumn. Radioactive ocean blobs form. A beached dinosaur resurrects near city docks. A classic monster film from the 50s sci-fi era.
