To begin this series, I waited until it was almost completed. It's definitely worth waiting to binge a little at a time. I give props to both the writer and the production team. I was really impressed with how well-made the show was. Every once and again, I feel we are treated to a series that rises above even the highest average show. 

IMO, what makes QOT work are the leads. The leads are excellent. For much of the show, they lock you into their world with their acting prowess. Kim Hyun and Kim Ji-woo pretty much carry the series. The solid writing and crisp direction blend with many of the smooth and kind of jazzy OSTs. 

I could go on and on. With that said, with all of the positive things, I did have some issues. I actually gave the show an 8.5, which for me is great! But it's more like an 8.7 or 8.8. So, I guess 9.0. There were a couple times in the 16 episodes I found myself thumbing through my phone. With all its great performances and moving episodes, there were small points of predictability and "convience" for the plot.

We can debate for the next 10 years about the happy vs. sad ending. But I will say that if he or she had died by episode 15, yes, it would have upset many, but it may have also, if done right, unleashed a floodgate of tears and emotions among fans. At no point in the series was I convinced or concerned that anyone could die. Especially after Baek Woo getting hit at 40 miles an hour by a car and ran away from the hospital, on foot...

Overall, the performances, the production, and most of the writing superseded the small issues. Anyone can nick pick, but some of the "pickyness" couldn't be ignored.
