Season 1 was really great.
In season 2, I think a lot of people expected some explanation. I think the creators intentionally left questions unanswered. Philosophical show, yes. Although I like that idea, I think the show lacks entertainment value for ordinary audience like me who needs to be tickled to fully appreciate the message.
While I applaud the brilliant premise, the show should have balanced the intentions of creators with the expectation from viewers. This has become pretty niche that only fans of cosmic genre will rave about, thus limiting its reach and seemingly failing at its purpose of imparting its philosophical message to wider audience.
Also, I wish there were more scenes with Min Hye Jin and the baby (now a cute toddler) just to soften the show, as there are a bunch of baddies and craziness almost the entire show. Min Hye-Jin and Park Jung-ja have very limited scenes you would think they were just supporting roles. The creators could have shown them more. as many fans of the first season attached the series to those characters. Bringing in new characters is fine, but they are given much more focus than those two main characters who only appear sporadically throughout the show.
Can't really help but sigh... I guess the creators opted for a different route deliberately to not satisfy the viewers.
Still, I am hoping for season 3. This series has great premise and potential. I still have hope that this can really be a philosophical masterpiece viewers can relate to if the succeeding season/s deliver.
