My favorite movies

My favorite movies is "Tesis", the first film of Alejandro Amenabar. It is a suspence film. the movie is about a journalis student who she is writting her thesis about the aggression in the media, so her thesis director is found dead when he was look for videos for her. Then she meets to Chema and Bosco, other journalishs students. Chema knows too much about "gore film" and Bosco was a boyfriend to other student who was murder in a "snuff movie". This is the theme , and when we know every character of the film, the director gets what we don't know who is who until the finish but I don't tell you the end.
