To start with, we have seen this kind of story in different variations many times before. Nothing new or original here. The film itself is dull, nauseatedly predictable, pretensions and awfully acted. The dialogues made me want to vomit. It is appears the film was made with a hand held camera and it times the shaking was pretty bad. I liked Ana de Armas in Knock Knock. I thought she did pretty good in it. She is the only one in Por un puñado de besos who was trying to actually act, even then her performance is rather weak, overacting in many scenes. Everybody else could have been easily replaced by robots, it is THAT bad. Jan Cornet, as a leading actor is unbelievably bad, looking sad and wrinkling his forehead was all he could do. There is zero on screen chemistry between two leading actors, I mean absolutely none. So skip it, unless you are a 12 years old girl. No sex, violence or profanity in this film.
