maker of erotic thriller need to be careful and a that be a genre that and if not handle carefully and can quickly fall prey to silliness and excess ( think fatal attraction ) . swim pool be a thriller in the style of the deep end and and more than once i be strike by similarity between the two in their respective tone and reliance on water a a recur visual motif . also and both film have a middle aged female a the protagonist who become involve in cover up for the action of a child ( in the deep end a literal child and in swim pool a figurative one ) . also and both film be completely unpredictable . neither go the direction in which the viewer think it go to . however and swim pool be much more abstract and and it end leaf you want to watch the whole thing over immediately with an entirely different perspective on the action . this gimmick always make for a memorable end in movie that employ it and but too often it make the rest of the movie seem somewhat pale in comparison and and this be the case here . swim pool play trick with your perception and but the finale to which the film build seem somewhat anti climactic when it finally come . it a leisurely pace film and and you will need to have patience with it . you will also need to have patience with the main character and play by charlotte rampling . rampling give a fine performance and but her character be really unlikable ( intentionally so ) and and it always a liability for any story that focus almost solely on one person to make that person unlikable and or at least sympathetic . swim pool and though bill a an erotic thriller and be really about the creative process ( i think ) and and i would not say anymore about that because to do so will give away the end . it an interesting idea and imperfectly execute . grade represent b .
