Lone Wolf and Cub/YMMV

Macekre: All mentions of the complicated clan warfare making up much of the driving point of the plot is removed in favor of vague references to "The Shogun". The film footage is actually comprised of most the second Lone Wolf & Cub movie, Babycart at the River Styx, with the first twelve minutes of the first movie, Sword of Vengeance bolted on to the front as an introduction.
Squick: Abe-no-Kaii practically oozes this trope. At one point, he decides that he's thirsty, but there's no well or other source of water nearby. So he orders his female companion to pee so that he can drink her urine instead. Later on, when he's waiting at a temple for Retsudo to arrive, Kai pretends to hang himself so that Retsudo won't kill him. But, in the process of waiting, he ends up urinating while hanging, then he gets hungry, so he climbs down to get something to eat. While doing that, he reasons that, since urine is salty, it'll make a good seasoning for rice. So he decides to make himself riceballs...by rolling the rice in the piss that was already on the floor. Seriously, this guy is disgusting.
Tear Jerker: Quite common. In one particularly notable example, Itto gets an assignment to take down a female fighter who has gone on a killing spree through the ranks of a feudal lord. During the encounter, Itto finds out that she is killing the many samurai in order to draw out a samurai officer who previously raped her. Even though he is bound by contract to kill the woman, Itto compares her quest to his own and stands back, allowing the woman to kill her tormentor, getting her revenge. Out of respect she then faces Itto in formal duel, even though the result is obvious. After having slain his target, Itto states that she can finally be at peace "in a place where nobody will ever harm her again". He then grants her a warrior's funeral and sheds Manly Tears.
The Woobie: Daigoro, often. The worst moment being what happens to his dog.
