It's definitely a big challenge to squeeze such a long story into one movie, as a result it's made into Part 1 & 2. This movie (Part 1) focuses mainly on introducing the characters and the different sects (e.g. Shaolin, Wu Dang, ErMei...), as well as the complicated conflicts among them; while Part 2... NOT sure yet, as it's NOT yet released (hee...).
The pace is good and it flows well from the beginning to the end! It kept me going on and I could hardly feel bored!
The role selection is a bit off! E.g. Getting 42-year-old Raymond Lam to play the role of an early 20's Zhang WuJi is NOT convincing at times. Besides, Donnie Yen is NOT old or 'there' enough to play the role of Zhang SanFeng. Instead, they shall consider Sammo Hung.
Basically, it's a very RUSHING movie, with the first 30 minutes introducing Zhang Wuji's background info (including his parents, grand-father, step-grand-father...); then it goes straight to the fight among the various sects. Due to time constraint, there is NO CHANCE for character development within each sect. Therefore, having known the storyline of this Jin Yong's novel in advanced is definitely an advantage.
The actions are ok - typical HK + China style - where they fly here and there while fighting, NO more NO less, at acceptable level.
Overall, it's an ok movie. I enjoyed watching it, and it's pretty entertaining! Despite the role selection issue + rushing pace, I am good with it! And I look forward to watching the Part 2 in the coming weeks.
