I didn't like Ning Que as a character, and I didn't like the actor playing him.
That and the slow uneven pacing were my main big problems.
The main romance is a bit (ok, at times a lot) uncomfortable.
The fighting is mostly good, but sometimes the CG sucks. And the fights are actually surprisingly rare.
Long Qing is a bitch, but I like him as a character.
Ye Hongye is bae, Bookworm Maniac is a sweet cinnamon bun.
(seriously, the supporting characters in this are better than the main ones.)

I'll watch season 2, but I need a break. This shit is LONG.
