When starting Story of Yanxi Palace I wasn't sure about it. Palace intrigues are nice a while, but 70 episodes? And within a harem?

But wow! It never ever gets boring! Not one episode I stalled, om tje contrary Iwas binge-watching it until the very end.

It's mainly the story about a sister (Wei YingLuo) who enters the palace as a maid to discover what happened to her sister, who died. She will go through many hardships throughout the series while trying to climb the ranks within the forbidden city.

The -:
I can't name any.
I will just state that you won't have any action-scenes (no fights, only perhaps small hand to hand fights). And if you watch for Xu Kai alone, don't, he is not the main character.
I was a little annoyed by the constant background music during conversations, but it's ok.
I didn't like the way they aged the men during the last few episodes, those beards were ridiculous.
One character was forgotten (a son).
As you see, I'm really being petty just to find some "-".

The +:
The storyline is incredible! How is it possible to write this many episodes of intrigues without getting boring? I'm still amazed by this fact.
The actors are amazing. The growth of all the characters is well depicted and each actor lived up to his role.
You get to know the life of the servants as well as the consorts and concubines.
The story contains heartbreaking scenes as well as happy moments, so as to leave you with a good feeling after each storyline.

All over all, this is more than just worth watching.
