The series' repetitive structure is a
feature, not a bug, as in the James Bond, "Star Wars" and Marvel
franchises. If you don't like them, you can complain that they recycle
the same images and situations. But if you like them, you can compare
them to sonatas or sonnets or three-chord pop songs, where part of the
fun lies in seeing what variations the artists can bring while
satisfying a rigid structure.
