While I think both parts of Kill Bill don't measure up to Reservoir Dogs or Pulp Fiction, I still think it deserves the win here. No offense to anybody who believes in the Bible or anything, but to me, the Passion of the Christ was an insufferable bore. If you eliminate the fact that it is a religious story, and you replace the characters with just modern day interpretations, the film is essentially just what people that dislike Jeff Hardy would equate to "a really long spot fest". The film doesn't have the typical plot structure. It ends at what should be the "return threshold" and thus has no denouement. Its sort of the reverse of a standard horror film. You introduce the killer(s), you introduce the protagonist(s), the characters aren't developed but you're supposed to care for them, and then it becomes X number of minutes of torture and "will so and so die" until eventually it happens, and then uh oh, resurrection. Now, some people will argue that that IS the story. That the whole point of it is to show how evil people can be and whatnot. But that doesn't mean its good story telling. Picture all those fanfic things over the years from different people that use the formula of "everyone that has previously been established has a huge fight, bigger than anything we've ever seen before, and then it ends". That's what Passion felt like to me...someone who is caught up in the "characters" (whether or not this is real is a religious debate, not a writer's debate) and is more interested in telling the action part of it than actually telling a story that has a message, a beginning/middle/end that closes things in a full circle, and so forth.
Kill Bill Vol 2 won't make it past the next round most likely, but I think the fact that it is able to actually go full circle. We're shown how she and Bill were before her pregnancy (exposition), we're shown how she changes her mind with her pregnancy and the incident where she is put in a coma (initial incident), we're shown more of the rampage that goes in the middle (rising action), we're shown that the daughter is still alive and she kills Bill by using the same move that was foreshadowed earlier on (climax) and finally we're shown and told that "all is right in the jungle" (resolution).
Kill Bill Vol. 2.
