Only Complaint...So Far

I have seen (most of) this movie (I couldn't wait to see all of it before I posted here). I like it so far; very sexy. I have experience in the d/s scene in Boston and I'm a little disappointed that there isn't more humor and/or just plain enjoyment emanating from the fetish characters while they are playing. Fetishism is fun, like most sex, but everyone is so grim faced! I know its not supposed to be a documentary, but the creators are aiming at some veracity since they have employed actual fetishists to portray themselves, so why not inject some joy in the play scenes?
