O Homem do Jazz

I have never in my 65 years wanted a movie to to not have a cliched, predictable ending as much as this one! It started with a lot of promise- it wasn't horrible or anything- and how often do we see a movie without a single actor we have seen or heard of before? Seems to me that if Perry had been thinking about this for 27 years or whatever...and I'm not even talking about the logical inconsistencies in the story, since that is so not the point! What is the point of having an imagination, a work ethic, tons of experience in the movie business- yes, I know about Medea but it's not like anyone else was involved in this movie!
