In summary, this adaptation has its pros and cons. For a modern wuxia drama I would say that it was quite ok. Much better than swordsman purely because of the finishing. At the end, YZ did not ruin the novel. I have to say that Chen Xiao is a talented actor. As for hardcore Jin Yong fans, it's best that you skip this one because there is no way you can compare it to the novel. Reason why I like the novel or any other novel more is because there are always more details in writing which is difficult to express in acting.
As for the haters, hope you grow up and move on
