I liked the seriousness of the series, but I did not like its ethics. The idea of revenge is something I am against in terms of making things right yourself. Also, the first 4 episodes seem like a completely different show than the last 4: while the first half focuses on a typical kind of conflict (with unexpected touches), the second half is more emotionally oriented - it deals with trauma and the unexplainable things it gets you to do. I would appreciate it more if the characters took responsibility for their actions rather than just treating everything as the world forcing it onto them. The only character that does that to some extent is Yeon Si Eun. Moreover, the ending of this season made me feel cold, sad, distressed and confused.
I am going to watch the second part as well, but it gave me a very weird impression and I can't really decide to what extent I liked it compared to which I simply got emotionally wrecked because of the continuous conflict of the show. Overall, I do believe it's a good series because of the effort to take on such a contemporary problem with new twists. Even if I do not agree with the way things are solved throughout the series, the fact that it's so messed up made it feel crazily real. That, I believe, is rare and it's what I most appreciate about Weak Hero Class 1.
