Donnie Yen really did well in this movie. He had his own style and way of killing people that was believable but also at the same time, somewhat superhuman or fantasy themed. For me, as a retired professional assassin that previously lived in a world of secret societies with hitmen and bounty hunters, they made a very realistic movie in my opinion. It made me think of my life when I was a professional hitman. Those were the days when I was just killing so many bad guys everyday. Now, I am retired and live a peaceful life. The movie made me reminisce of a life I once lived.
