For several years now I have been collecting the really bad things (as well as the really good) about the film biz. It is a substantial list. One day I will order it and check it for duplicates. For now, I think it might be helpful to look at all of them in one sitting. Do it before you embark on your next film. Do it when you are trying to assess your priorities. Do not fear. These are not roadblocks, but opportunities.

I am working on a similar post for 2014 (32 Things) and there is a lot on that list already.
Note: As of December 2014, and not counting any inadvertent duplicates, the total list of Suck In The Film Biz over the last 6 years is 162 Things. What are you going to do about it?
