First of all, I must say I only saw the first part of this film which lasts about 90 minutes. According to the people who were presenting it, the first part is the most accessible to modern, non-Argentine viewers.
This film is a lengthy diatribe against the smothering influence of European powers in Argentine cultural and economic life. The anger of the film makers was very effectively expressed by the film's rapid fire pacing, its fiery narration and its harsh, thundering soundtrack. The soundtrack was the strongest element, and its relentless pounding really drove the film maker's points home.
This film seemed less like a documentary than a filmed version of a revolutionary pamphlet. The single mindedness of the views expressed and the solution proposed, namely violent revolt, seemed immature and insufficiently reasoned. The views expressed seemed more inspired by bloody minded hatred for outside meddlers than sympathy for the oppressed and marginalized native Argentinians. It was very much a "shoot first and ask questions later" attitude. This is not the sort of attitude that I would want to see shown by my leaders if I were an Argentinian.
I suppose much of the bitter hatefulness of this movie can be understood by considering that it is a reaction to very oppressive censorship. Such a movie is acceptable as a preliminary blast against the oppressors, but one would hope that calmer, clearer heads would prevail afterwards. The attitude of the film makers here, in this film, really borders on the unhinged, the demented.
