"and 10 minutes ripping off other movies."
There is a difference between ripping off and paying homage. The whole premise of Kill Bill is built off of paying homage to the various movies, genres, ect that Quintin grew up watching. With this comes all the "cartoon violence" as it applies to the particular genre.
Also: If you go to this movie expecting Reservoir Dogs 2: Mr. Pink's Kungfu Revenge, you will be disappointed. So don't.
