Your question of “whether or not an alternative Frankenstein has ever been written” is an interesting thought experiment. I was about to say that no, it’s never been done. But then I realized this is exactly what Mel Brooks’ Young Frankenstein is about. Interesting that only a parody has seemed to consider your question. This suggests that satire can approach topics that other narrative forms can’t, and it also makes me wonder if Brooks’ movie is in fact more serious that most people give it credit for.
