The two always appear at the same time on various occasions like an appointment, and in the process, Get to know each other. Ryan, like Bill, is taking revenge, and he seems to be inextricably linked to Bill's tragic childhood.
Western movie reviews
A typical Western from an Italian director. The title of the Western movie uses biblical phrases. The music is very brilliant, as expected from the master Ennio Morricone, the general structure of "Kill Bill" is borrowed from this film, and some of the music is directly borrowed. Friends who like Quentin movies should not miss it. The yellow sand in the desert flies by horseshoes, and the Qiang flute and pipa have sore throats. Privately I thought that Wong Kar-wai's "Evil in the East and Poison in the West" was also quite influenced by Western films. But there is one thing I don't understand, why are those robbers robbing so much money?
