The movie is great, my favorite Beat Takeshi movie, unfortunately the DVD itself is quite bad.
First, it's not an anamorphic transfer, so you have to use the zoom if you have a widescreen TV. Motion in dimly lit scenes is smeared, colors aren't saturated enough, and the whole image is very soft, without crisp details.
I also have the VHS from ICA Projects, and it actually looks better overall than the DVD.
The second problem are the subtitles, the translation is horrible at times when compared to the VHS. One great piece of dialog goes something like this:
- You're the stupid one
- No, you are the stupid thing
There are also US and Hong Kong DVD releases of Sonatine, but I haven't had the chance to check them out yet.
