It really isn't as good as the novel, Ernesto Sabato did a genius work by portraying Castel as a psycho lover who was too focused on the idea of Maria, his lover cheating him. He wasn't able to enjoy his relationship with her and their future together ends in a tragedy when Castel's insecurities lead him to kill her. In a way, the novel reflects the way of thinking of the 21 century man, unsure, liar, doubtful, etc. It is only fair to judge this movie by reading the novel and personally, I recommend you to read the novel. The characters take more importance, especially Castel whose feelings are the most important part of this story. It is also remarkable that the actors weren't that good at portraying this characters, Maria didn't seem to be the same melancholic person who lived with regret like she did in the novel just like Castel didn't seem to be that much insecure and they both made their romance look like something unbelievable and dumb.
