After seeing ‘Piranha, Piranha’ recently, I noticed online film discussions where people express disappointment because they considered the title derivative (I won't reveal any plot points), and that the movie is an unpleasant experience. My response to that is simply 'to each their own', as I found it quite enjoyable. It isn't on par with films like ‘Piranha’, ‘Jaws’ or ‘Moby Dick’, but considering what it attempts, I think it succeeds admirably. William Smith, much like Jack Palance and Henry Silva, possesses a certain undeniable quality; you might dislike his performances, but you have to acknowledge them, and there's probably a part of every actor that envies someone with his screen presence. He seems impervious to anything, completely in command of his own fate. Anyone who inconveniences him is removed from the picture, and he takes what he wants. This film fully embraces that persona through Smith’s character, Caribe. The movie combines elements reminiscent of 'Deliverance' and ‘The Most Dangerous Game’. It certainly isn't a masterpiece, but it’s far from as terrible as some people claim. And calling it a copycat of Dante’s thriller is inaccurate, since it was released six years earlier (and three years before ‘Jaws’ popularized this kind of film). What I struggle to understand is that around the same period, in an even more isolated region of South America and with equally challenging actors, Werner Herzog created 'Aguirre, the Wrath of God', a true masterpiece…
