It broke my heart because the same thing happened in Bucharest, just two years later. Same outdoor pyrotechnics, same foam ceilling, only one exit, and an impossible long wait for justice in a country that is so devoid of it. I don't think everything has to be perfect to be deeply moved by a tragedy that shouldn't have happened. To me the acting was great, I felt each of one of those parents pain, even though I am sure that the pain the real parents endured is incomprehensible. A tragedy like this goes well beyond the victims and their family and friends, it ripples through society, even if society is moving so painfully slowly.
Is it one the best series that I have seen? Certainly not! But it moved me deeply and that is something. After all, art should tell the truth.
