I know, I probably didn't make any friends with that statement. ;-)

If it pleases the court;

Role-playing and cos-play are an attempt to make the film (any film) into a sort of reality, for lack of a better term. To me - that takes away the magic of the film. I don't want the film to be real, I want it to be an escape from reality. A chance to be transported. That desire for the film to be an escape from reality is the same reason I don't watch behind the scenes documentaries. Just a personal choice.
