I've been lucky enough to watch this movie in Italian & understand it & I think that, if properly read, it can be considered a very interesting approach to ancient myths. It is actually based on the myth of Oreste (I don't know the exact translation in English of this name) & it shows the destiny of a boy who has to revenge the death of his father. This couldn't have happened in a different context nowadays, the Italian Camorra is one of the "institutions" based on personal revenge, more or less like the Mafia. It is true that for a non-expert it might appear as a bunch of people killing each other, but this is not the point of the movie. It has at least 2 levels of interpretation &, if read in the key of ancient myths, it actually makes sense.
