Thoroughly enjoyable. After the first episode, totally hooked. Extremely good in every way. The acting was superb from both main and almost all supporting cast. Almost every character were multifaceted and interesting. Wonderfully, unexpectedly humorous. For non-Chinese speaking viewers: watching with a good translator makes will make the experience even better. Unfortunately, I have not found a stand out sub to recommend. Still should be an excellent watch for non-Chinese speaker even though may miss some of the jokes, play on words, and plot subtlety.
Intriguing plot twist and turns, multi-dimensional schemes, philosophical, touching, something to laugh about, cry about, to 'ahhh' about, ponder about, get excited about, to cheer about. There were some moments when things didn't seem to quite make sense, or seemed disappointing. Every time, I just trusted the makers, and the significance was revealed later.
I watched the entire season twice, and it was just as good the second time around in the process of discovering many things I actually missed the first time. Highly recommend watching!!
