Simo's glare and smile

I think http://www.filmblerg.com/2014/09/08/miff-review-concrete-night-2013/ nails it; most of the film stands on the intriguing glares and smiles of Simo, as well as on the beautiful although distressing post-industrial views of Helsinki. (Views which are probably disappearing right now, as Vuosaari and the rest of the city are being rebuilt at an impressing speed.)
