1. Characters: kill the wolf 1 has distinctive images of Donnie Yen and Jason Wu, and their actions are well designed, which makes people unforgettable. However, the characters in Kill the Wolf 2 are not distinctive enough, and the overall performance is not as good as that in kill the wolf 1.
2. Background music: The violin background music of kill the wolf 1 is natural and unobtrusive, and its style is dark and sad. An English song is used in the background music of Kill Wolf 2, which is too abrupt, so kill the wolf 1 is better than Kill Wolf 2.
