I watched Shogun Assassin of Kill Bill vol. 2 fame this week courtesy of Mr. Torsten. Very good film. The plot is totally nonsensical but there is lots of blood-shed and gore. It's incomprehensible as it is apparently a dubbed hatchet job of the first 2 films of the Lone Wolf and Cub series. Worth checking out, but I bet watching all the films in the right order would be better.
Addendum: This is my favourite piece of dialogue in the entire film. The music in the background should tell you what the soundtrack is like as well.
