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.
Values Dissonance: Though Albert's mother is not a particularly sympathetic character, her casual racism towards (the Hispanic) Rosie—Played for Laughs, even—can be jarring to modern audiences. Modern scripts for the play include alternative lines that soften her dialogue a tad.
The 1963 movie notably avoids this. Mrs. Peterson still hates Rosie, but it's because she is upset that Rosie will take her "baby," Albert, from her. In fact, Rosie's "Hispanic-ness" is barely even mentioned.
The lyrics of 'How Lovely To Be A Woman' can be cringe inducing.
'How lovely to be a woman/and have one job to do/to pick out a boy and train him/and then when you are through/you make him the man you want him to be...'
