Lone Wolf and Cub: Baby Cart at the River Styx -- 89pts. This is the second, and usually considered best, of the six film series, from the 70s, based on the manga books of Lone Wolf and Cub. Lone Wolf is a disgraced executioner who travels the roads picking up assassination jobs. Cub is his three year old son who Lone Wolf pushes in a baby cart. A tricked out baby cart that has more gadgets than the Aston Martin in Goldfinger. When these two come around you know there's going to be blood gushing out of various cuts and detached arms, fingers, legs and noses will be flying.
These films obviously had a big influence on Tarantino as is clear from his directly quoting from them in the Kill Bill movies. Also if you are a Star Wars fan (I'm not) you will recognize some themes in Mandalorian with Baby Yoda (wasn't adult Yoda enough?) were also taken from these samurai films.
