I so much wanted this film to be great! I so badly wanted it to be great and unique that I think -- to some extent -- I even managed to overlook its multiple issues. It's not a decent piece of cinema. The editing is awkward and the acting is poor. The latter makes sense as there are no professional actors in Iran and -- as you mentioned -- the people we see are simply the musicians the movie is all about. And this also explains why the music videos prepared especially for this film are its most powerful moments.

I wish it could have been better but perhaps it simply couldn't in the conditions it was shot and then edited.

I wrote a longer piece about this one a while back: The Voice of the New Generation (NO ONE KNOWS ABOUT PERSIAN CATS review)
