It appreciate that a director takes the time to post regarding his work. I personally did not like the film. My father said he had a few laughs. My wife fell asleep. I know you had nothing to do with it, but I wish there were subtitles on the DVD.
The book was really great, but the material did not lend itself to a film. Maybe you could use this film as pilot and re-release it as a sitcom. I think I would like it better tightly edited and in 30 minute doses. Also, although Barry is a funny writer he is not that appealing on film. Sorry your film did not get wider release, but I am sure you will make a buck on the DVD.
All the best,
