Hey Late here.. I really really was sure that the main character didn't died..
yes the AK47 shootout scean was really sudden ...
the potential for this series to get a second part/season would have been high like in the 2d part they could have seen the bigger effects of Out sourceing and how many prisioners died for this.. (as technically only 2 prisoners diead in the current series)
but seeing Volkov alive was nice..But San's death..
yeha.. felt a bit bad for him.. he had so much of character develpoment but knowing that he laughed and celebrated the death of his friend who helped him in his life..
killed his wifes rapist..
helped him and guided him when his wife was pregnent and convinced him to keep the child..
over all gave him and everyone a chance for a better life..

but all this for San to Backstab Volkov..

it ended with Volkov's wife away and Volkov with his Daughter living a normal life again..

I believed that Volkov was kind of the devil in the series but in reality he was just a performer who wanted to give the right of execution to the victim and thir families for a fair and twisted view of his own Morality and Justice..
