These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Alternativecharacter Interpretation: Depending on how you look at it the Japanese managers were stubborn jerks who mistreated their American workers with unrealistic expectations or the Japanese managers were Innocently Insensitive to American cultural norms and were simply tough but fair in their pursuit of getting more from the American workers while the American workers themselves were lazy, uncooperative and ungrateful to their new employers.
Unintentionally Unsympathetic: Buster (the George Wendt character). He loses some sympathy points when he knocks down the one Japanese player during the baseball game, and loses even more later on when he harasses Umeki Kazihiro - Oishi's wife - at the grocery store following his demotion to janitor when Umeki herself had not personally wronged him.
