a dirty shame be a john water film about a prudish and uptight mid western woman who and after have concussion in a motor vehicle accident and become a rave sex addict . although i be a bit of a john water fan a dirty shame be a pretty big shame and a disappointment . i guess society and comedy have move on a bit from drag queen eat doggie do ( see pink flamingo ) . show and film like south park and wonder showzen and team america seem to push the envelope in term of bad taste comedy . a dirty shame just seem to fall a little short of that push the envelope in bad taste name . most of the sexual discussion feel not quite as raunchy a sex in the city or even jerry springer . most thing about this movie feel a little on the amateurish side the acting and the cinematography and the script . however one plus be the selma blair character although it sort of felt it be a little underused . overall a dirty shame be a big disappointment . john water appear not to be push that bad taste envelope anymore . perhaps he need to return to more kitsch mainstream territory ( a la hairspray ) .
