Mick Anglo was to Marvelman what Jerry Siegel was to Superman, the creator of a character later transformed by other writers. There is a difference of scale. MM has had two other writers whereas Superman became an industry:
the multi-media Superman;
the re-created Marvelman, later renamed Miracleman;
the Smallville TV series that began as a Superman prequel but became a distinct story and also proliferated into other media.
MM and Smallville, both good in different ways, are so dissimilar that it is easy to forget their common origin.
