If you believe the marketing that is what this is. And in a way the marketing guys got it right. This is actually what you should expect from this movie. Maybe they also should have mentioned, that it is an extended music video. Every 3 to 4 minutes there is a song coming up, sometimes played as a story evolution or as a montage piece. But you will hear quite a few music pieces before the movie is over. And if you like the music, at least you will be entertained in one category.
The question is if the director did music videos prior to this (though it seems like a given). The flashy cuts, the music, the style overall would suggest so. I wouldn't go as far as to compare it with Kidulthood. I don't think it could stand a comparison and it would be unfair to the movie. It's nothing big and has quite a few flaws and will only appeal to a certain group of people. But that doesn't mean it's completely bad. It has a few nice things going for it ... you just have to find them (and it won't be easy)
