Oops, late reply!

I didn't like it basically because it seems to me as if they just got some people off the street and let them play some music. (Apart from Sezen Aksu then..)
Somehow after I had seen it I didn't feel like going to Istanbul anymore (but which I love to do now of course ).

I can't exactly point down why I didn't like it, but it just didn't give me a good feeling about Istanbul :S.

I like this film because Mercan Dede featured in the movie is my cousin.

In one of the quoted articles Istanbul is mentioned as Turkish capital which is wrong. If you are writing an article on a movie describing the culture and music of a city you should at least know that that city is not the capital of the country.

I don't trust many of those critics. I once read an article that praised the music of Bueno Vista Social Club but she found the instrumentsa a bit out of tune. Did she watch the documentary carefully she would discover for herself that tuning instruments slightly off key is one of the most distinctive characteristics of the Cuban music.
