I have read the manga, and was quite sceptic about watching its adaptation.... But surprisingly, I totally loved it.
The cast selected for each character is really impressive. Their performance as per the original characters in the manga is really accurately portrayed. Before watching I was worried about bad casting. But after watching Xu Kai and gang, I am worried that like most other typical chinese drama series, they will change the actors! If they do, I don't think I will be able to watch it!
Though at times the drama does seem to drag certain events but then the overall acting of Xu Kai and the supporting cast, their awesome action scenes and well rounded special effects ... all of these fill up any other discrepancy that was there...!
The only awesome character completely missing in the drama is the coolest Dog from Savage Lands....!!!! I guess the special effects just for the dog scenes would have been too much!
