A film review: "Sangre eterna"

Carmilla, a journalism student, meets a group of friends that play a role-game called "Eternal Blood" ("Sangre eterna"). She gets interested in this hobby by "M", a young man she met in a philosophy conference. "M" gets Carmilla into the role game, but in a strange party at an abandoned house, the group meet "Dahmer", an unusual young guy who makes rituals about vampirism and step by step he begins to influence his friends. "M" realizes that the situation is unusual and that some of them are actually being transformed into vampires. In the investigation of the origin of these myths, "M" finds the way to revert the group's process

"Sangre Eterna" is a chilean movie. But it's also one of the most awful movies that I've never seen. Carmilla (Blanca Lewin) was promoted as the main character, as we can see in the sign above. But it's just in the first 20 minutes; the real main character is "M", and the actor who plays this role (Juan Pablo Ogalde) is terrible! He doesn't have any emotion! Just like a lot of actors in this movie, and that's really annoying on a movie. Also, the special effects are ridiculous, it's imposible to feel the struggle of the situation. I believe that a chilean movie could be as good as any movie from other countries, so I don't forgive this thing just because it's a chilean film.
