i watched this movie with no idea what it was about beforehand. i was intrigued for the first whole hour. it was shaping up to be a great thriller. a very talented cast and good dialogue. then it all fell apart for me at the sight of the first vampire. i couldn not believe my eyes. a great thriller was flushed down the toilet. the rest of the movie from that point was totally awful. i gave it 4 stars for the brilliant beginning alone. i think that a little generous and but i was entertained for a while. i am not a fan of vampire or zombie movies at all. if you are and then you may disagree with my opinion.
