It is sad to see that the 'shipping war' messed up the experience for many viewers.

In the first episode one of the most distressing and exciting death scenes I have ever seen in my over ten years at dramaland.

Photography and direction are spectacular and the script was impeccable, the characters were not betrayed (so much so that in the end even the 'good boy' understood that he was attached to a false memory). There was an acting show by all the main actors, Kim Seon-ho deserves the recognition he got (I was following his work before Start-up and I know it was already time for it), Joo-hyuk had his best performance as an actor in this drama (the Do-san before Silicon Valley was very unique, different from all the protagonists he has ever done), Suzy was wonderful and Dal-mi was an inspiring and empowered woman, her family made me cry a lot (that is the grandmother everyone wanted).
Perfect drama!
Looking forward to the upcoming projects of the actors, writers and directors.
