Yashida then drugs Wolverine and has his evil mutant doctor inject heart-weakening parasites into his body through the traditional Japanese medicinal art of creeping into his bed and making out with him.

How He Dropped the Ball:
Rather than dragging Wolverine's paralyzed ass back to his lab for immediate healing-factor theft, Yashida decides to let Wolverine go and fakes his own death for no conceivable reason.
Yashida even goes to the trouble of staging a huge public funeral for himself. His granddaughter, fresh off a substantial inheritance, becomes targeted by the Yakuza, and Wolverine feels obligated to protect her, because he and Yashida were super best friends. Yashida (still pretending to be dead) then has his granddaughter kidnapped in order to lure Wolverine into a trap, wherein he finally reveals (twist!) that he's been alive this whole time! Then he attempts to use a giant suit of fantasy science armor to kill Wolverine and steal his healing powers.

By this time, nobody in the audience can even remember what this movie is about.
The movie is hoping you'll be so shocked by the plot twist that you won't stop and realize how laughably difficult the villain made things on himself: Why bother with the circuitous evil plan when Yashida had Wolverine drugged and defenseless within the confines of his millionaire fortress 30 minutes into the film?
Couldn't he have just climbed into his battle suit and stolen Wolverine's chi while he was passed out in the guest room? He was clearly drugged enough to let the Sex Doctor sneak up on him and give him heartworms. There was literally no need for any of this other bullshit. This movie should've been the equivalent of Wolverine waking up in a bathtub full of ice without his kidney.
