The use of visual effects have been widely acclaimed and the almost comic book style of the movie are its most striking features. It is in stark contrast to recent Kung Fu movies that have made an impact in the West, such as Crouching Tiger, Hidden Dragon and Hero. Despite the computer-generated imagery and cartoonish scenes in the second half of the movie, the movie pays tribute to many famous Kung Fu film veterans from the 1970s who were all real martial artists in their own right. Many early fight scenes were packed with real Chinese martial arts. In addition, the "Buddhist Palm" style of Kung Fu featured throughout the movie is a style of Kung Fu cited by Chinese people whenever a fighting style involving open fists is used.
