When I first read the summary, I was intrigued and I was looking forward to seeing a bit more about how the Nie Sect works "behind the scenes". I also really liked the ending scene (those that have seen the movie know what I am talking about). It was great seeing Nie Huaisang and Nie Mingjue interact with each other as brothers and the flashbacks to them being younger are sweet, but sadly the power-dynamic was way off. Except for about 3 1/2 scenes the Red Blade Master was always shown as an absolute Badass while Nie Huaisang was always painted as the damsel in distress that needs his brother to save his ass and a bit useless. Yes, the Red Blade Master is a great leader but his little brother isn't too shabby either, making use of the fact that he is so often underestimated.

I will recommend it, since it is a nice piece of further information but it would be at the bottom of the list about which order to watch all the parts in.
