Fontanarrosa's drawing style is a true legacy and more than adequate to commemorate José Hernández's character, the gaucho Martín Fierro. In this film, which has a certain failed epic tone, that style is the most important thing. Because I believe that the great flaw was its multiple direction (more than three directors), which has clearly affected the result, hasty decisions, with a story that hardly recovers the verses of Hernández's poem. Technically, the animation looks unnatural and choppy, and figure and background often blend poorly. Sometimes the drawings are excellent, other times they look like scribbles. And the night scenes are indecipherable, so bad is the decision to light them. Another thing is the chosen music. When it's not folk music, an orchestration sounds that has almost nothing transcendent and seems like a Hollywood pastiche of no importance: canned compositions, without vitality, absurd clichés. In spite of everything, lost the potential and the great contribution of Fontanarrosa, a recommendable film even though it could have been a huge universal and eternal classic. Pity.
