Due to the fact that the movies came out so far apart in conjunction with the abscence of TV reruns, continuity wasnt particularly important to the studio. The best example of this is Frankenstein, who granted supported 2 stellar sequels, quickly denigrated in quality as the series was continually dredged out for another installment. The last 2 classic Universal Frankenstein films are on parr with thr likes of Superman 3 and 4 in terms of how astoundingly mishandled they are. The 5th installment was especially insulting as it sees the monster himself (now blind, mute, and still with igor's brain) play second fiddle in his own feature as wolfman takes center stage.
Ofcourse, once the Frankenstein series died (the most popular series of the universal monsters) they decided to drop continuity altogether in exchange for depending on brand recognition. In turn leaving us with installments like the invisible woman, the creature walks among us, the mummy's hand, and so on.
