After reading the other review on SPCNET I thought I would share my own. I realise that this series is an adaptation from a very popular novel; however, seeing as I cannot understand Chinese, let alone read it, I can only evaluate on the series itself. When only the elements of plot, character, and acting are concerned, I found this series to be quite interesting and well done.
Felix's performance was vintage Felix as the tragic hero. I thought him to be an excellent choice for the role. Maggie Siu's performance was excellent as well. She was extremely convincing in portraying the heroine who would do anything for the man she loved. Their onscreen chemistry was added bonus to the series as they looked good as a pair. Hugo's Ng was great as the villain who took revenge for his family's masacre. As far as casting went, I believe that TVB did a great job when choosing actors for this series. The only character that didn't leave a great impression with me was Kim Mo's second love interest. Although, the character did a lot for Kim Mo, I didn't see a powerful chemistry between Felix and her like I did between Felix and Maggie.
The plot of the series was a very typical plot with respect to searching for a lost child after twenty years and the fact that basically everyone died in it. However, I found it interesting how the series was able to depict good and bad in a society. Hugo's character, although used deceiving means in order to take revenge for his household's death, was seen as a "good" guy in society's eyes, yet he was the true villain in the series. However, Maggie's character and Gordon Liu's character, although trained assassins and would kill innocent people at the drop of a hat, could actually be looked at as honourable and caring characters. They showed more loyalty than any other character in the series, whether it be to their teacher or to the ones they loved. Kudos to the two actors.
I must admit that, even though this series did not end the way I would have liked it to. It still remains well written and well acted. I believe that it's a series that's worth watching if you don't have any expectations to the novel. I can only evaluate it on the series itself and not it's depiction to the book. If you like Maggie Siu, Felix Wong, and Hugo Ng as, more-or-less, typed cast characters and want to judge the notion of good and evil, this series got it.
