It's a great series. I loved it. Season 1 is good but it's ending is not so happy. 2nd season is also good still some died. And at the third season still some died and some left. What would it take to make the ending happy? In the last season people left alone with their grief. What should we do? Compare people left are more important than people died. If there would be fourth season make all died person back in again. I just love happy endings. But really I just loved it because of its contents specially in emotions.
