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: Stranger Than Fiction
Crowning Music of Awesome: Harold Crick singing Whole Wide World leading into Wreckless Eric's rendition of the song while he finally gets the girl
Genius Bonus: All the characters' last names are references to famous mathematicians and scientists.
And there are a number of visual references to René Magritte paintings, particularly The Son of Man.
He Really Can Act: Will Ferrel is mostly known for his comic roles, but damn if this movie doesn't prove he can pull off a dramatic role. Crick's distress when he's told that he must accept his death in order to make Karen's book work feels strikingly genuine.
Vindicated by History: Though far from critically panned, the movie didn't quite get the type of praise it deserved (mostly because many people were skeptical about Will Ferrel being able to pull off a dramatic role and a lot of the praise ends up sounding like "who knew Ferrel could do this?" rather than "it's a good movie"). However, today it is often regarded as one of the best movies of 2006, with many people wondering why Ferrel didn't get at least nominated for Best Actor at the Oscars.
