- Big-Lipped Alligator Moment: Monk dancing. Zen bowling. Prom bungee jumping. The last half of movie is... odd.
- Fight Scene Failure: Michael Ironside had to telegraph his punches by a considerable margin for the Colonel's final fight with Miyagi.
- Jerkass Woobie: Julie tends to drift in this territory. She's disrespectful to her grandmother and Miyagi, especially the latter when he does very little to warrant the treatment he receives. However, she lost her parents recently, has no friends except for an injured hawk (and, from her first day in school, a male colleague originally in the Alpha Force named Eric McGowan, who eventually becomes her boyfriend), and is constantly being harassed by an arrogant jerk who abuses his powers by punishing her. Her grandmother seems to be in denial about her mother's death, even calling her "Susan" (her mother's name) at one time.
- Special Effect Failure: Was it Zen that caused the monk's bowling ball to leap back out of the gutter, or was it the plainly obvious pop-out lever in the gutter that did the trick?
- They Wasted a Perfectly Good Character: Louisa Pierce, Julie's grandmother. She never shows after the dinner in which Mr. Miyagi promises her he will help her get over her anger, and is only mentioned in passing in the "Karate Waltz" scene, during which he states Louisa taught him how to waltz in France.
- They Wasted a Perfectly Good Plot:
- How Julie's relationship with her grandmother would improve after Mr. Miyagi had gotten her out of her sorrow.
- Couldn't have Mr. Miyagi and Louisa dated? Was that "beautiful Louisa" line a way of him flirting with her, albeit in a discrete and respectful manner?
- Both Louisa and Julie grieving after the deaths of Susan and her husband.
