For a biographical movie is good, mainly because, unlike to others in this genre, the actors speaks in the languages of the real people they portraits. But for a boxing movie, at times fails with the romantic drama scenes but mainly for the over egocentric personality of the main character, Roberto Durán. Also the script doesn't show the public enough matches. The highlights of the film, obviously, is Edgar Ramirez performance, but in my opinion, gives me a mixed perspective...in one hand, a confident and charismatic Durán, in the other hand, sadly, a man who blames his father for leaving his family and uses that as an excuse for his hate to U.S.A. is kinda annoying, also he thinks he's unstoppable even with his coach, Ray Arcel, played by Robert de Niro. Despite all this, the simple script is saved by some aspects. One is the costume design, because the movie occurs in many years, and the clothes tells us the time In which the characters live. The good technical aspects, like photography, sound mixing and editing, and film editing too, gives the film a better look. In overall, this movie is better enjoyed if you seek a mix between sports, drama and romance but not at its best.
