A Jedi Shall Not Know Anger. Nor Hatred. Nor Love.
Why it is hard sci-fi
Soft. Star Wars at its least scientific. The Kamino cloning facility is the films only nod to a real biological process, and the film treats clones as a renewable industrial input. The procedural worldbuilding is in the clone-army logistics rather than the science.
Science inside it
Industrial-scale somatic cell cloning with accelerated growth and behavioural conditioning. The film treats the clones as a working military doctrine, which is more interesting than the mechanism. The Kaminoans have a working pipeline from genome to deployment-ready trooper in roughly half a normal lifespan.
