Good movie. The music, good god, the music in the movie is fabulous. Thumbs up right there.
The cinematography was superb as well. I'm not going to give any spoilers, but there is a particular fight scene in Japan near the end of the movie that is positively better than anything I've ever seen. Ever. It's brutally violent. Limbs, blood, and gore fly in every direction and it's executed so very well.
This is a very violent movie. So violent, that it made me and my friend laugh. There are parts where heads and limbs get hacked off and the blood will literally spurt in every direction. It gets to be so over the top, that it's funny and that would most likely be the single biggest flaw in the movie. Now, I do know that the level of violence and blood comes from the movie's anime roots, but Tarantino overdid it in some scenes.
I also get the feeling that Tarantino is a bit on the pretentious side. I have no real evidence for this, just a feeling. And from what I've seen of the guy on talk shows, he scares the hell outta me.
But yes, I would recommend this movie for anyone who doesn't mind a high level of violence, blood and gore. It's very well executed and Uma Thurman is fantastic in the leading role.
