Hanzo is crazy.... Gotta love, ShintarĂ´ Katsu one of my favorite actors of all time considering Zatoichi. The first time I seen hanzo beat his junk with a club, I wanted to cry for the man. Crazy ass Series.
Lone Wolf and Cub is bad ass..... I love the first 3 or 4 but as the series goes on it gets bad. They get into the whole ninja digging in the dirt and ghosts and ****. If you like Lone Wolf and Cub you should check out Mute Samurai its a old Japanese tv series, which Tomisaburo Wakayama (lone wolf) plays the main character.
Dead Beat Dawn was cool, Love the whole throat rip out scene. I wouldnt have known about it but a friend of mine grew up in Germany on a Army Base and use to watch this as a kid. It took him years himself to get a copy of it himself, but soon as it came in the mail he had me over watching it.
I am going to have to check out Midnight confessions.... it looks promising.
As for my own Suggestion for exploitative movie.....
I would suggest
Bohachi.... I was going to post a youtube Trailer. But I couldnt find a trailer with out breasts showing

And I am not to sure about forum rules here. But Its pretty much Hack and Slash and Breasts.
