with out ruin all the film twist and turn ( i recommend reading a few review a possible before see the film ) and this be a great little thriller . very stylish cinematography and good character . the twist ( there be only a few and so do not let them be ruin by careless reviewer . ) be unpredictable and mostly . great film and only complaint would be the very horror slasher end which leave me a little disappointed give such an intelligent premise . and no i do not think that will ruin anything for the first time viewer .
