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.
Troubled Production: No major catastrophes, but this movie was made back in the early 90's, when digital effects were still in their infancy. This means that they had to stage the scenes down to the smallest detail, and any slight unplanned movement would ruin a take, which had the effect of exhausting the actors. Later on, Meryl said that while she was proud of the movie and her work in it, never again would she do a movie so effects-heavy.
Unfortunate Implications: The Aesop about aging is all well and good, however, it's easier for Ernest to be the one who rejects living forever because men are not as stigmatized as women are for getting older. Madeline, Helen, and even Lisle, are all women that sought to preserve their youth and beauty because they live in a society where women are constantly judged and valued based on their age and their looks. But the women are all portrayed as grotesquely self-absorbed and shallow regarding their looks. A more fitting Aesop to take from this film would be that forcing standards on women they cannot maintain can turn them into parodies of themselves.
