Yes, Ending was not satisfactory for the audience. Its not like we are expecting bad things to win but atleast some satisfying scenes should be there in the last episode. Its like we are wasting our time to watch a good going series to be end like this. Its not bad ending but it is what we predicted it from the start. We know the reality. But we wanted some unreal and unexpected ending which would fullfill both reality and audience. Otherwise ofcourse it is a good thriller experience and must watch. Anime at its best!!!!
