The Dunwich Horror/YMMV

"He was, however, exceedingly ugly despite his appearance of brilliancy; there being something almost goatish or animalistic about his thick lips, large-pored, yellowish skin, coarse crinkly hair, and oddly elongated ears."
 * Fridge Logic: Where did Wilbur's Y chromosome come from? Males inherit that from their fathers (females have XX). I doubt an Eldritch Abomination has anything resembling human genetic material. (Or would Lovecraft have not known this?)
 * If you're going to worry about a Y chromosome, you might first want to worry about just how an Eldritch Abomination is even able to breed with humans in the first place.
 * You're sure we're talking about typical in vivo breeding to begin with?
 * Wilbur ends up over nine feet tall. Where's he getting his clothes from? Magic Pants?
 * Hollywood Homely: In the book, Wilbur Whateley is a Humanoid Abomination. In the 1970 movie, he's Dean Stockwell.
 * Unfortunate Implications: The townsfolk refer to Wilbur as "Lavinia's black brat." Why, hello, Lovecraft's racism, glad to see you could make it again.
 * And not to mention the fact that he is dark despite his human family (where his human aspects would have come from) being white. Note that some of his facial features are reminiscent of blackface (as is true of the Deep Ones as well).


 * The Woobie: Lavinia. She's unattractive, deformed, isolated, lives in squalor with a batshit insane father, and is eventually.
