It's very hard to review "Los cronocrímenes" without spoiling the fun of watching the movie and seeing how the different stories within the main plot outline keep unraveling ever so intelligently. Let's just say that it all starts out with a man watching through his binoculars and spotting something that catches his eye. He follows his curiosity, and that will be the start of some extremely unusual, mysterious, and intriguing events involving this man, a mysterious stalker with his head wrapped in a pink bandage, a naked girl in the woods, and a young scientist.
"Los cronocrímenes" is a terrific movie, one that was made with a low budget, a reduced cast, and very few settings. It combines sci-fi/fantasy, mystery, action, and also sprinkles of comedy -I found myself laughing out loud more than once while watching this. It's a twisted, tragic, cynical sense of humor that I find very fitted to the Spanish way of being and general look on life.
You may enjoy "Los cronocrímenes" for what it is, taking it at face value, and enjoying the twists and turns (and even if you think you've got it figured out, it keeps the ability to surprise you all along). You may also take a deeper look into it. Each viewer sees a different story and message in a movie; for me, personally, besides an extremely entertaining and thoughtful mystery and action movie, "Los cronocrímenes" offers good insight into the human soul, our deepest and darkest motivations for things, and how the line between good and evil is ever so blurry.
