The village trying to make money off its infamous past is a fine idea (provided it's not handled in a way that's too silly). The Frankenstein descendant opening a tourist attraction, however, seems like a step too far for me. I think it would be a much better idea if she were coming to town to continue her ancestor's experiments, and the source of friction with the townsfolk could then be that they're concerned she'll scare off the tourists by resurrecting "the real thing," instead of just cashing-in on stories like the town has been. It's worth noting that the town citizenry in the later FRANKENSTEIN sequels hate the Frankenstein family, for the most part.
My other concern (which is a strong word, but I'll use it) is this: with the modern setting, I think you run the risk of the whole thing feeling vaguely like a fan-fiction-y, off-brand imitation sort of thing. But that's dependent on other design factors. Is the land going to look like the European Streets set from the Universal Hollywood lot, where most of the town exteriors for the old films were shot? Are the Monster character designs themselves going to be identifiable as the Universal versions of the characters, or will they be more generic interpretations? What is the overall "tone" of the land going to be like -- campy or straightforward?
