Over the ending credits Nathan Lane talks about having to really do some low things to survive in show business and apologizes for having taken this role, referring to it as being one of the lowest things he has ever done, but while he sounds sincere who knows if he is.
This is a raunchy, filthy, dirty, not-funny (to me) movie, anti-everything from sex, gender, religion, life, living---you name it--without (for me) one laugh.
Here are various critical takes on this movie:
