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.
Harsher in Hindsight: The end of the movie where Andrew willingly gives up his life to be happy (fulfilling his dreams of being recognized as human, that is) becomes a whole lot darker when you take into account Robin William's own suicide in 2014.
not to mention near the end of the film, seeing Robin Williams in aging prosthetics makeup is a bit odd and unerving now since he tragically didn't live that old.
