PROS:
Brilliant acting by Fan Bing Bing. The chemistry between Li Zhi & Meiniang is awesome. I love the costumes. Even insignificant concubines have pretty dresses. The music is really catchy. Overall very enojyable.
BTW this show might be a little confusing at first because there are many characters and clans but you'll get used to it later on. Also, skip the intro/theme song and the outro cuz they contain spoilers.
CONS:
The years and months in this show go by kinda fast. Also, some parts are a little historically inaccurate like the Princess Anding thing. Also, It would've been better if they finished off Taizong quicker and showed us more Meiniang x Zhinu & it would've been more accurate too because irl Meiniang spent more time with Li Zhi than Li Shimin/Taizong.
Anyway, the drama is interesting but I suggest you to watch a historical drama before this cuz it might be confusing if u haven't watched a historical show before and don't know about the whole consort concubine system. I recommend Empress Ki.
