I really don't get why people are complaining this sequel saying it didn't live up to its name. Yes the prequel was hell of a ride but this was too. The only complaint I had was i wished they stuck to one story rather than many. Maybe connecting them in a bit better way would have helped. One thing that was similar in both the dramas was the amazing and strong cast. Both dramas had seasoned actors giving their best and doing hell of an awesome job at it. I honestly did not see where people were coming form saying this was bad. For me this was just as good as the previous.

Also another thing, do not go into this expecting a happy ending. My heart was racing the entire time scared as to who would die next. More than half the team died and I didn't even know what to feel at the end. You didn't know who the hell was the good guy and who was the bad guy till the end. Up till the ending sequence I was not sure who was good and who was bad which in my opinion was one of the best aspects of the drama. As per the last one and as per all of the writer's works this drama too heavily relied on comradeship which is what makes me totally addicted to this writer's work. If you go see his resume you can literally see how many awesome dramas the scriptwriter has done.

Well I wouldn't mind another season with the same cast, maybe make it a twist and add the old cast too yet still I'm kinda excited for the movie which would have taken place between these two seasons.

Another plus point, make sure you watch after the ending sequence in the last episode. You will be in for a treat ;)
