The film was directed by my brother because he knew my love for cinema "second-rate, with a mixture of mysticism and a certain level of philosophy." And hit the bull's eye!
However, the film seemed to me deliberate: there are spiritual Indian bandits, and stupid drug dealers, and Lynch Frenchman with a peculiar understanding of time, and a secret in caves and abandoned houses. In the B-movie genre, this is accentuated (one name "Bomb with a shotgun" says everything), and here the authors seem to be interesting, which reduces my assessment.
The rest of the film is interesting. I'm glad my brother showed it.
