...which annoyed me, because the production, cinematography and direction are amazing. Ferro didn't feel natural speaking, apparently everyone thinks he's pretty and provably that's attractive in an actor and main role (even if he doesn't look much like the real life Carlos Puch), but his lines felt very forced and sounded very unnatural, it's more noticeable if you understand the original language and Argentinian accent. I understand Carlos Puch is an absolute psychopath (excuse me if it's not the exact technical medical definition of what he is, but you get what I mean) and being inexpressive and lack of emotion in extreme situations could be part of his personality, but when Ferro is trying to act "normal" and talking to family or friends he looks and sounds very unconvincing. Still, besides this few scenes when I didn't like Ferro's performance, the movie is very well produced and I did enjoy it very much. There's also the fact that a couple of his worst crimes were left untold in the movie, which is weird, as they would have added a lot of weight and define better how bizarre and sinister Carlos is. Still, good movie, but because of (in my opinion, of course) the main role's bad casting, I have to lower my score quite a bit.
