We saw the Bride (Uma Thurman) kill literally dozens, perhaps a hundred people or so in "Vol.1," now here, she only has and succeeds at killing one. (Well, perhaps she killed two.) You don't need to have seen "Vol. 1"; to enjoy "Vol. 2", although it does help, despite the opening chapter of "Vol. 2" giving us more then enough explanation to catch up. That said, "Vol. 2" is the better film. It's sly in how it's better though. Tarantino for instance, played up O-Ren as a dangerous character in "Vol. !" , and yet, in "Vol. 2" completely downplayed Budd (Michael Madsen) as a serious threat for her, which is also what The Bride does which is how she ends up in her most precarious situation yet as she inexplicably falls right into his trap and gets buried alive.
Of course, it's Tarantino's sick sense of humor to then give us the one last nod to the martial arts genre, by showing The Bride gets beat the hell up all the time by Pai Mei (Gordon Liu, who also played one of O-Ren's top associates in "Vol. 1") I think arguably, that sequence is the most important of all the chapters, 'cause it answers so much, and yet, sets up everything that comes after. It's the first time, we really get to meet Bill (David Carradine) and really see the full scope of his relationship with The Bride; we had met him, finally, onscreen, at the beginning of the movie where we get the intense explanation of what exactly happened at that wedding chapel, but it shows us how she's managed to do everything she's done up to this point, as well as get our hero to literally punch her way out of the obstacle that she can't get out of. All these things are difficult to do in writing, separately, especially for a film, but doing it all together, in a more novel structure, is really special. While it's easy to focus on stylized directing in Tarantino's films, especially his more Leone-esque takes and ideas in "Kill Bill Vol. 2", and this is arguably his best directed film, I think the writing is what really puts Tarantino apart. I talked about this is my Canon entry on "Kill Bill Vol. 1" but perhaps it needs to be emphasized, Tarantino writes movies the way others write books, and that challenge has rewarded him greatly over the years.
For instance, the relationship between Elle Driver (Daryl Hannah) and the two brothers, Bill and Budd is peculiar, to say the least. She seems to be the loosest canon of them all, even we find out, as having turned on her mentor before without any particular emotional response. She's downright sociopathic, except towards Bill, who she seems eerily devoted to. I gotta admit, that in my head canon for the movie, I suspected that she was also related to Bill and Budd (Michael Madsen) as their sister, and there's some insinuation of this, but apparently that's not the case as she's apparently Bill's replacement for The Bride, although her complete disdain for Budd, who's path has clearly divulged heavily from Bill's as these brothers lives have definitely gone off somewhere along the way, makes it seem like she's definitely as close to the family as you can get, without being related, even if it's not the family either of them would want.
It also would arguably be the best, because it's the most iconic and fun of these movies, even in the #MeToo era where this genre is saturating the market, including the recent Best Picture nominee, "Promising Young Woman", "Kill Bill Vol. 1" and "Kill Bill Vol. 2" are going to be the one that we're gonna keep going back to because as much as "Promising Young Woman" might be what female getting revenge on the people and system who literally went after you, actually might look like in the real world, "Kill Bill" is what you want it to be, and imagine how it would be like. It's the perfect fantasy version of how you'd actually imagine getting that kind of vengeance, and that's why it still feels so damn satisfying all these years later. So much more memorable as well. It might not have been the one that garnered the awards attention that it should've but I think long after the tropes created by "Pulp Fiction" are gonna feel passe, "Kill Bill" is still gonna explode off the screen and remain indelible on the mind.
Sometimes we just need to go through a long epic struggle to get some bloody satisfaction, ain't that right, Kiddo?
