1. some actors (and even famous and experienced ones) were so off.. the 'funny' gangster, TOP, Lee Jin Wook, Park Gyu Young and even Park Haneul.. maybe they added too many characters and they all wanted to shine.. they tried to add too much personality in little time and it was just too much. Gong Yoo was great though
2. voting got tiring. if you're releasing only 7 eps and plan to show much more side stories and povs, how about not repeating things ?
3. games are less interesting. the only moment I was really excited during the whole show was when the outcasts (girls and old lady) were in that group game and everyone was cheering for them (I was also cheering from home). to me this was the highlight of this season.
4. what was the game leader doing there? did it add anything to the plot? we already knew who he was, and he wasn't charismatic enough to make us care about him nor he managed to create a strong bond with the other characters to make the treason a shock.. bad and unnecessary idea that took space from the main plot.

as a whole, this felt less natural and human. they just threw a lot of different characters and stories at us, so we didn't connect with anyone. it felt very amateur.. :(
