The whole series is a journey of understanding for me. The overall story arc is revealed in bits and pieces. Imagine a huge garden in spring. Once the flowers start to bloom, one begins to see a pattern and the viewer starts to think that "Ah-ha, that is what the picture looks like." As more flowers bloom, more patterns are revealed which congregate to create an even bigger pattern. Each episode is like a single flower blooming. The main character is faced with a seemingly impossible task and he is comparable to the legendary Kong MIng of the Three Kingdoms era. Each step, each solution is logical without any "contrived" situations that insult my intelligence.
I've watched the whole series twice through and through and more when it comes to certain "emotional," "triumphant," "ah-ha" segments. Clues are littered everywhere for the audience to catch and these become obvious on the second run through. I highly recommend it to everyone who likes an insightful experience. This is not for "heavy Kung Fu" action movie afficionados although there are some action scenes sprinkled throughout the series.
