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.
YMMV: Madame Butterfly
Fair for Its Day: Nowadays, the play gets criticism for codifying the stereotype of Asian women as fragile and nothing without their Western men, but in its time it was meant to condemn the cruelty of the West towards the East via making Butterfly a victim of Pinkerton's thoughtlessness and jerk assery.
What an Idiot: People who are less receptive to Butterfly's woobieness (and even some who are) believe that, while Pinkerton is a massive ass, Butterfly also commited severe mistakes. She was given either warnings, help offers and/or advice by people like Suzuki, Gorou (who even told her he could get her a new engagement) and even Sharpless but spurned it all to wait for Pinkerton's return, still blindly believing that he would come back to her. And it did NOT end well.
