I'm an Indian residing in Prague with A1 level of spoken Czech. I watched this movie since it was screened with English subtitles (they should do this type more often). I thoroughly enjoyed the movie. It's a low-budget but nice, feel-good movie. The protagonist old man has acted extremely well. Others were average to good in my opinion.
From a different perspective - I'd especially recommend this movie to expats who want to improve their A1/A2 Czech language. The dialogues were simple and someone with A2 competency should follow the without any trouble. I could follow most of them with my A1.
Again - loved this movie :)
