The Oxford Murders

I see a little part of this film, only 30 minutes, and I think is a good film, and better then Sherlock Holmes. Elijah Wood plays Martin, an american student at the University of Oxford who wants Arthur Seldom (John Hurt) at his thesis supervisor. Martin knows at perfection the life of the Arthur. Martin stays in a room of a old women's house, this old women life with his daugther, they relation is very sincere independent of his bad behaviour between they. Martin go to a public lecture to listen Seldom, and to impress him, Martin question one affirmation of Seldom, but he humiliate Martin, later things that his idea is stupid and he things to go home, when Martin go to his office, he encounters with Podorov, who explain his negative experience to become a Seldom's student. When Martin go to the house of the old women, he find Arthur who goes to visit his old friend, the old women, when they enter to the house they find the old women, who is death.
