MONSTER MASHUPS #80

 And here we have another Japanese comedy about a harem of sexy monster-girls, MONSTER GIRL DOCTOR, which includes a wide variety of monster-girls constantly pursuing a handsome but mostly oblivious human doctor, reviewed here. 

MONSTER MASHUPS #79

I've finished a review of 2015's FRANKENSTEIN VS. THE MUMMY. Since the two creatures are co-equal figures in the narrative, this might also stand as a crossover-- more on which elsewhere, perhaps.

Addendum: though I may never get around to putting the rationale into words, I would now regard this as a "null-crossover," a term coined on ARCHETYPAL ARCHIVE, which applies to a film where one established character crosses over with one only appears once but does not generate his own "character cosmos." This stands in contrast to "spin-off" characters who may have no history when they first appear, tied to some established character, but who do go on to generate such a history, even if only through just one repeat appearance.
