First, I wanna say that I think the story of Trujillo and his assassination should never have been made into a movie based on the book "La Fiesta del Chivo." Don't get me wrong I love the book and I think Vargas Llosa did a masterful job of telling a complicated story but he had 500+ pages to do it. Luis Llosa only has about 2 hours so as a result a lot of the characters including some of the people who should have been the main characters feel incomplete and relegated to supporting roles. The irony of all this is that the only characters in the film who get their due are the young Urania and her father and they never even existed.
All that being said I probably would have ended up liking the film had Luis Llosa not directed it. This story needed somebody more subtle who would let the drama play out. Luis seems to think that the best way to show drama is by showing slow motion shots of guns being locked and loaded. The cast was good and there is no more beautiful setting that Dominican Republic but this story deserved a lot better than this film.
