Vampires combusting in sunlight’s one of my least favourite tropes in vampire lore. I don’t begrudge Nosferatu for introducing it, but it’s become grossly overused in the decades since.
Also dislike the common “patchwork corpse” approach towards Frankenstein’s Monster. Shelley never actually describes how the creature was made in her novel; there’s evidence he may’ve been closer to a homunculus than a scientific zombie. That’s all beside the point, though. The physical description of the monster in the book is striking in-and-of itself and would translate well to screen; it’s criminal how few filmmakers have even made a cursory attempt.
