This is the review for part 2. But the rating I give here, is for the show as a whole!
I indeed really liked the first 10-15 episodes for part 2.
But sadly the second half of part 2 segment was slightly dissapointing to me.
And with Part 1, I liked the second half more than the first half.

The stroy and the way it progressed in the first 10 episodes of part 2 was really interesting and had funny moments.
I really liked the emperor and empress as well as the consort. These side characters for this show will be some
of the most memorable side characters from a historical c-drama I think.
The acting by our two main leads was really good. I really liked Zhao Lu si, she is really likeable and nice to look at.
I would definitely keep an eye on her future works.
Leo Wu is one of my favourites, ever since I saw him in NIF. He does his role really well in this show too.
With some similarity to his previous The Long Ballad. The other support characters were really good too.

I do like the family bonding and conflicts that were displayed on this show.
And how they were resolved and the many issues shown within those royal families.
The Music was good also, those instrumentals they did was pretty nice and blended well with the scenes.
I think (Galaxy Sigh) is the one I liked the most out of the 3.
I would definitely rewatch the good and satisfying moments this drama had.
Yet the unecessary conflicts that were rushed, I wouldn't.

The ending was good, but yes it could have been a more satisfying one.
I guess they were trying to end it with a fade out, representing the title of the drama.
Because I understood that much from what I saw at the end!
Hence this Drama is wonderfully directed and acted. Yet couple of things would have made it more better.
