I truly enjoyed the movie as it is exciting to watch from start til the end. There's some jokes involved as well (if you are running man china aka keep running fan, as you will notice there's cameo appearance captain Deng chao on one quick screen) the chemistry between actor and actress simply just superb. Even through its Li Chen first director film (he also involved in script writing part as well) the story line is not too messy.
For the past few years, china production movies seriously beat Hong Kong movies. As I found sky hunter touches your heart deeply as you will feel their dedication for the love for their countries.
I seriously recommended Sky Hunter if you are a fan of action movies.
