Quick Review V:

It's really quick (I mean 6 episodes) and the characters are pretty realistic in their design. The story line was very short and kind of difficult to get incredibly invested into, but because it's so short, it's still a very good watch. It's definitely worth a watch.

Longer Review V:

I'm so sad that it's only 6 episodes. The cast was great and I really enjoyed them, especially Fu Kang An's actor. It was also great to see so much of the old cast reunited (Yuan Chun Wang, Wei Yingluo, etc.)!
The story line was amazing as well. I thought it was very engaging. The leads had some pretty good chemistry. Also, I loved the plotting of it all, as well as the references to the old story (ie. Fu Kang An's mysterious identity). The best part, in my opinion, was actually Fu Kang An's identity. Who is his actual dad? We will never know. :)
I really liked the music- especially considering that we never listened to parts of the OST before in Story of Yanxi Palace. In this short spin off, I discovered that the OST from Yanxi wasn't just WOOO WOOOO WOOOO.
Overall, I definitely recommend watching this! It's amazing!
