[Thrillerboy]

Has no one here seen that Swedish (I believe) porn that did a take on different movie monsters? There was one scene that involved a female werewolf (though, the actual TF was offscreen), and all it ended up being was a chick with contacts, fangs, and some mild prosthetics to make her brow look more canine. For what little they used, it was actually good makeup.

To answer the question, I don't think there is a lot of common ground here. What we get off on is the actual changes themselves. Be it bones crunching, digits and organs rearranging, tails growing, or faces pushing out into muzzles. What the average pron viewer is looking for is hot chick, tits, ass, vag, and said girl taking it up multiple holes before being covered in man gravy. You can sexualize the transformation as much as you can (see Missa's clips), but at the end of the day, unless that's what you're specifically looking for, it's not gonna do much for you. (Of course, there are always a few exceptions...)
