Overall, a good movie with a good story and a good direction. There is no dramatic event, but 'The Happiest Day in the Life of Olli Maki' narrates Olli's journey to the most important game in his life calmly, peacefully, and honestly just like what everyday looks like for everyone. Because the movie does not add ANY salt or pepper, it loses intensity and density along the way especially toward the ending. The championship boxing match is supposed to be the peak or the burst of emotion and highlight of the film, but there isn't any emotion stored for more than an hour. The direction of the match does not meet the expectation. If you look at it from another perspective, it's a great achievement to lead 90 minutes without any particular events with a strong plot.
