First of all, i won't be comparing this RoCH with other similar titles. Story wise, it's JY's novel adaptation with 80% similarity, 20% of it is improvisations, telling new story arc that's not in the book. I don't really like the story of this JY's book so i just give 7,5 point. Legend of Condor Heroes has better story in my opinion.
Acting is just average. Contrary to many people who praise Leo Wu as young Yang Guo, i think he is over-acted. This series has the worst version of Zhou Botong who always scream whenever he talks. And, i agree with most people Michelle Chen is miscasted as Xiao Longnu.
One more minus from acting is many unnecessary & illogical kissing scenes. A guy who just meet a girl can kiss her without even knowing each other? Man, this is totally unacceptable, right?
Special effects are outdated. Fighting scenes are just average.
Music, i don't pay attention to it but i think it's pretty good.
Rewatch? Nah, i never rewatch a show, and this one is a sure "no".
