I bought this series from an Amazon seller after reading the book and seeing some clips on Youtube. Aside from the annoying sub-heading Ren Ying Ying mentions (which I agree is really stupid), I'm finding it a great series. I can hardly persuade myself to turn it off and go to bed. I've only watched half of it so far, but at the rate I'm going I'll finish it in another week.
I liked Li Yapeng as Guo Jing in LOCH '03, but Linghu Chong gives him much more to do, even though LHC does spend half the time being wounded. I have come to really, really like Li Yapeng as a result of his performance as Linghu Chong.
Almost all of the other casting is good, too. The only actor I haven't liked so far is the guy playing Yu Canghai - he's just a bit too hammy. Tian Boguang wasn't exactly what I expected - I thought he'd be younger and more handsome - but I already liked that actor and I like the way he played the character. The actor playing Yue Buqun has a perfect gravity and grace, and the actress portraying his wife is perfectly matched to him. The guy playing Lin Pingzhi looks just the way I imagined him when I read the book.
I think this series is in danger of superseding ROCH '06 as my favorite. All the sad parts where Linghu Chong's life gets more and more miserable make me cry, and the romance between him and Ying Ying is really charming. I don't even mind the changes to the story.
Plus, the music is just awesome. I wish I could get a CD of it. I love the opening and closing credit themes, Ying Ying's theme, and the Xiao Ao Jiang Hu tune.
