I have no idea how inspired by Frankenstein Lovecraft might be, but basically Frankenstein is the better version of this in every single way. You should genuinely read that instead.
Apparently according to Wikipedia Lovecraft hated writing this. Not sure how true that is, but it really shows through the writing.

Which is disappointing, because I actually quite liked the movie version of it. Sure, it wasn’t great, but it was quite enjoyable. I know I shouldn’t be disappointed because obviously it wasn’t going to be too similar but wow this was just a waste of time.

Oh, and this is the single-handedly most racist Lovecraft work I’ve read yet. By far.
