Being a child of the 80s, born in Bulgaria, I found it easy to relate to the movie setting from communist time. It brought back memories, made me smile when thinking of the things I also used to do or experience. But if that was all to this movie, it would have been merely a successful exploitation of people's memories of times that were drastically different than the current ones (in what way, that is a differents story...).
But what actually made me fall in love with this movie and write this comment is the fact that it goes beyond the socialism cliche and actually tells a story that almost anyone of us can relate to. The story of "what if...".
