I'm really sorry to say (i'm a big S. Segura fan) that the movie completely (i would save 1 gag) fails to...everything. Acting is poor, the story is so commonplace, but mostly, it is an insult to hard rock, as if explained from my grandpa's point of view. Shame... Nothing to do with Segura's work as a director, which i really recommend everybody, the Spanish grotesque at its very best. But in this case I think the director, full of stereotyped poses about the rock scene in his own country, caricatures what he does not even know, or that is what it seems. Plus, the movie cannot find the rhythm or the tone. We know is possible to make fun of a human tribe and respect it, (Detroit Rock City, This is Spinal Tap), but this... oops, deeply sorry to be so negative.
