I assume that the novel is better than the series. Series misses at least one important element (the love affair WWX and LZ). I found the plot tedious, repetitive and illogical. CGI is very bad. Dropped it after 20 episodes.

I liked the acting of of WWX and some other characters.

It was incomprehensible to me how a brilliant free spirit like WWX suddenly joined the immature brother's, in my opinion, simplistic and illogical narrative that he was ultimately responsible for pretty much everything that went wrong. When a story/character becomes too unbelievable that you can no longer identify with it, it becomes boring.
