As a Greek citizen I must say that was a great work from almost all the aspects. It's not a crime serie or a mystery one, so you don't need to wait for any plot twist or a big reveal. The serie shows its identity from the very beginning. It's about friendship, love, concern and life. During the journey of the serie you are able to pass through many different lives and cultures. Until a point I can feel the serie since I'm also a foreign to another country and have seen and experience many similar situations, but not at the same level ofc.
As a greek I can confirm that the serie shows us many stereotypic characters or even circumstances but that doesn't mean that all are wrong, exacerbated I would say. I'm not mad about it, I have seen hundreds of French and Italian movies and I know that it's something ordinary for them and they even use it for their own cultures as well. I'm gonna repeat myself, the serie doesn't lie, but doesn't show us the other side of the coin too. Same thing with the locations that they decide to show us. Athens besides the graphite and the abandoned buildings it also has other amazing locations, that gives another atmosphere to the whole city.
Personally I loved it for its mini stories of its characters, the drama and power for life that they gave us. I believe that it's a serie that has to be recommended from schools so the students learn more about the value of a human life and that respect is the definition that all of us need to have in our dictionary.
