Later that same monday: Now that I am at recommendations I will shop the movie "Half Nelsson" (2006/Ryan Fleck) that led a quiet life in danish and international cinemas in spite of a wellearned Oscar nomination for leading male actor Ryan Gisling in the part of Mr. Dunne:

Mr. Dunne, an idealistic teacher who thrives on teaching and motivation but who has completely lost his attachment to the surrounding society and people - a disillusioned force of talent.
He slowly slides backwards into abuse but on the way there he strikes up a peculiar quiet friendship with one of his students, also facing a much faster downfall.
The quiet opposition the two of them poses narrates the movie safely through without any extra layers, but basically its a very heartfelt and in many ways a confirmative existenstial movie.
