You bring up an interesting point. just looking at the evolution of movies:
Think of all the people who are interested in history when they watch a period piece. Speaking from experience, my brain explodes when the film makers get something wrong. With vampires, you always have an expert. How about vampires using their abilities for special effects. Or lycanthropic animal trainers to make sure that the animals do what the director needs the first time without, I don't know, killing the lead.

I haven't read the newer Anita and I think I might be glad for that...
heteroflexible indeed.
