I agree with Pete S.
Even if it is a wind up, or someone trying to make a few bob, most of the replies have just been downright rude.
The film, if not a wind up, will still be made, whether we have any input or not.
If you contribute and it is not a true reflection, then you have a right to criticise.
If you do not contribute and it is crap, you really can't complain, because you had a chance to make it authentic/true reflection and chose not to.
If the guy is sincere about making the movie, I wonder what he thinks of the people on the Northern Soul scene from the replies he has received?
The funny thing is, if he went to a venue and asked the same questions, most of you would bend over backwards to help him.
