You see, Kill Bill Vol. 1 basicly is a homage to japanese revenge movies, especially modern ones (the almost comic-style use of colours, or the stylized fight scene almost directly taken from "Twillight Samurai") and some influences of classic japanese movies like "Lady Snowblood" and "Godzilla". The movie is very fast paced for a Tarantino movie, with a high level of violence (even for a Tarantino movie

Kill Bill Vol. 2 however, is entirely different. Although it continues the story, the style is not compareable to the first one. Vol. 2 is based more on chinese kung fu films (for example old Shaw Brothers flicks), but also has a high influence from westerns and even horror flicks (the grave scene for example reminds me of certain Fulci movies

These facts let me to be believe that - even if Tarantino once intended it to be one very long movie - it is now two movies, that do not fit together - at least not in their current state. They are too different.
I believe, if Tarantino would do a complete version of this movie one day - which I doubt - he'll do much more than just put them together. Knowing his previous work, I'd rather think that he would completely redit this movie, not just cut here and there, and extend here and there, maybe even change the order of the chapters. We all know how his movies work, you are totally confused until Tarantino explains it to us (this is the main reason I would never watch a Tarantino movie in chronological order, it would lose it's dynamic).
That all said, I still was interested in "The Whole Bloody" affair. And I was very surprised how good Gaijins work is. As I told earlier, there are great differences in pacing between the two movies. Gaijin took great care of that, by editing in some of the deleted scenes - the "Bill kicks ass" scene really enhances Part 2 - although I think it was correct to lift it from the two part version - and lifting some other scenes. The movie really feels more complete now, and you can't really tell where Gaijin edited the movie (except of course the Bill scene

Gaijin's work is fun and never boring throughout the four hours lenght and I really enjoyed it. Although I have to admit, that this is probably not what Tarantino has originally inteded

But in the end, I still prefer the movie as two independent parts, due to the break in style.
Thank you very much for four hours of fun, Gaijin.
Oh, by the way, I changed my mind about Kill Bill some time ago. For me, Jackie Brown is definetely the best of Tarantinos movies (not that anything is wrong with KB)
