I don't think you really need to justify your decisions Dave
. But at least you care enough to provide evidence.
I would argue though, isn't desperation quiz also a scenario movie? Yes it might not have a storyline but it's at least the models doing something other just standing there. That for me is enough of a 'scenario', no need to get the models to act or add in bondage. It's just...there is only so many times you can ask "so do you have any stories" in one movie set
Then most of remainder of the movie(s) turns into awarkard silence/laughter
Oh yeah, while statistics don't lie, also just want to point out that it's kind of different when it's a multi-model shoot. If there are two models with no scenario then at least they 'play off' each other. When it's a single model shoot you get what I described above IMO.
