I thought it was absolutely amazing - favourite foreign-langauge film of last year. The corridor fight was stunning, and its certainly not for the squeamish, but it deserves to go beyond the Extreme Asia enthusiasts, and the Cannes Film Festival did that for it - nice one QT!
It comes out on DVD on February 28th, and look at the extras! Originally Tartan were a little stingy (but I'm sure that was to do to difficulties getting hold of foreign material), but now:
