The story is about principles and loyalty. 'Love in between' may tell that it is not about romance. Even though there are three protagonist couples, there are barely important decisions of actions taken by them based on love. All is about putting principles and loyalty first. That is my take from watching the whole series.

The story could be made more simple, but yet still interesting. Too many 'new-facts' introduced in the middle of the story. The existence of hidden emperor is very important to the whole storyline, but not elaborated into the drama adequately and early enough, leaving the impression that it is shoved in to the audience in the middle of the drama for the sake of making the story a bit complicated. Also, I am not so sure with the ending and I think it could have been done better.

As a wuxia fan, I was a bit disappointed that the Yun Luo's martial art skill with her special weapon 'love in between' is not explored to make the entire series more interesting. Zuo Qing Ci also too weak physically to fit in such storyline - but maybe those are what in the original story. My favorite character is Shen Man Qing, portrayed well by Deng Yu Li.

Overall, it is a good movie to watch. Oh, and I love the theme song. :)
