Absolutely a 10. Excellent writing, directing, editing, casting and acting. Good sound track. A carefully crafted story with nuanced depictions of characters and their emotions. Lots of details for side characters resulting in a richer, more realistic/life-like experience. Does a good job of portraying aspects of the media business without intruding into the story. The first season is light and fluffy by comparison.

Pay close attention in the first few episodes to place the flash backs/flash forwards to different time periods in the correct order. Narrative voice-over by different characters gives it a literary feel, and the juxtaposition of different voices emphasizes the different ways characters are experiencing the same situation. Don't be afraid to back it up if its a little confusing.

Some reviewers have made negative comments regarding the credibility and emotional inconsistency of the Ji Woo character . Is Ji Woo actually credible as a character that would exist in the real world? Since when do we require our fiction to be 100% realistic? Ji Woo epitomizes the emotionally stunted, those who are unable to understand and communicate their own feelings and emotional pain. To some extent all of us can be that person. This movie is about how we struggle with facing bad feelings. The emotional discontinuities in Ji Woo that some complain about, I interpret as merely shorthand. This is not a "how to" to resolve communication problems; it isn't showing us how they resolved them. It is pointing out the high cost of these communication problems. I can attest from personal experience the high cost of failing to communicate and the extended amount of time it takes to get to a position of acceptable communication. So maybe I rate this season so highly because it most closely matches my own experiences.
