It was a surprise for sure.
1) The movie looks shockingly good. Yes, it was supposedly made for cheap, there are some instances of visibly lacking CG. But the way it's lit, shot, coloured etc. - amazing. Stuff is clear, visible, intentional, pleasant to the eye. Looks a lot like a 90s movie, but with a wider palette.

2) It's, unfortunately, a black tanktop vanity project for Donnie Yen. The guy cannot pass for a man in his 30s, effectively half his real age. Yen also does not have the acting range needed for this kind of character.
The funny/lighthearted parts are not that funny or lighthearted and the serious moments are awkward, feel extremely long and overly pathos-filled. (for an example, time the wine-bowl scene. That could've easily been edited down some, with more of an emotional impact.)

3) The story is whatever. The more wuxia/series movies I watch, the more I realize I don't enjoy Jin Yong/Jin Yong-style stories. It is what it is, I'm sure fans of the book are outraged about stuff.

4) The fights however, are incredibly good. Excellent, thrilling, fucking cool as hell. If you looked at the 90s wuxia and imagined a logical evolution with advances in filmmaking, this is what it would be.
No notes.
(also goes to show what you can do on a budget if you have real martial artists instead of celebrity idols in your cast)
Whatever the fuck the new Kung Fu Cult Master did with the flashy CG bullshit, this is the opposite of that.

5) Minor point, but I really enjoy this "gritty" portrayal of the jianghu people. Everyone's wrinkly, greasy and rugged. The costumes are very different looking and quite lovely.
It's not quite The Blade, but it's miles and miles from the usual "wuxia" you see in cdramas nowadays.

Overall: Meh, but watch it for the fights.
