I was watching the Oscar winning film, The Secret in Their Eyes (2009), a thoroughly highly polished and well made police procedural that also was quite boring because of the slow pacing and even duller characters. Struggling through the slow drying cement of a film when an hour into it, the story went to ... of all places... a big time soccer match.
That broke my spirit completely so I had to shut the movie off before exposing myself to a even more painful death by boredom experience!
