I've never known a horror film display a genuinely moving love story, whilst simultaneously developing suspense, anticipation, fear and scares throughout (I jumped out of my seat on numerous occasions). A superb performance from Belén Rueda, as well as from the supporting cast combined with inventive direction and camera work make this a thoroughly enjoyable and truly frightening film.
One of the things that surprised me most was the use of blank screen for quite a sustained period, which in film could be compared to dead air on the radio, yet this was incorporated so skilfully and fittingly, and considering the films narrative, I can't think of anything more suitable and compelling (other than the camera flash scene perhaps). There are many techniques used which put us very much in the position of the heroine by limiting what we can see, as her vision deteriorates so does our perception of the world and the more the film progresses, the less we know or can be certain of and as we doubt her perceptions, so too do we doubt our own. From this premise, our fears escalate and the impact of her physical and psychological traumas truly take hold.
As mentioned by a previous reviewer, the film does draw from Hitchcock and in a very positive way, in that less is more and what is concealed from us is what's terrifying because it is left to our imagination and preys on our own fears, encouraged throughout by our compassion for the heroine. Compelled by Belén's marvellous performance depicting the trauma of her condition, together with the cinematic techniques employed to further our sympathies with her predicament, this is an excellent psychological thriller/horror film, imbued with love, fear, loneliness and darkness which will not fail to satisfy. When you don't know where terror lurks is what makes a film all the more terrifying, a premise of which Julia's Eye's is a shining example.
