As usual there are many epic and eloquent reviews out there already. I'd like to just add a very quick take.

Executive Summary: You should watch this only if you will be very into a literary, poetic story with a small stage feel.

The Good:
Bai Lu is awesome as usual. She is the reason I could finish this drama. She is beautiful and cute and her natural acting in an unnatural story is what made this worth the watch.
The cute/comedic moments were very well done and were a nice respite from the slow pace and bad vibes.

The Sub-Optimal
This story is the slowest, least intense drama I have managed to finish. Really too slow for me.
The secondary characters were not fleshed out well. A couple of the secondary female characters were very well done and acted (by Wang Yue Yi and Wang Rui Xin).
