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.
Award Snub: Three songs earned nominations for the Best Song Oscar. Hence, the vote got split, and "Falling Slowly" from Once won the statuette.
Reviewers of the movie said Amy Adams deserved a Best Actress Oscar, but she did not receive a nomination.
Ear Worm: Just try to get that theme song out of your head...
Family-Unfriendly Aesop: Probably unintentional, but it's A-OK to break off a long-standing relationship to marry a girl you've known a week. Which adds more fuel to the Parody/Not a Parody fire — isn't that kinda how all Disney romances go? How many of the Disney Princesses know their princes for much longer than that before the Happily Ever After?
Well technically, Nancy ran off with Edward and we never really know how long Giselle and Robert date before marrying. They're together in the montage, but then two characters have published books and Giselle is running a fashion business, so yeah...
Hilarious in Hindsight: There is a poster for Superman Returns in Times square when Edward first arrives. This was originally a reference to James Marsden's role in the film but becomes humourous now that Amy Adams plays Lois Lane in Man of Steel. For extra points, James Marsden originally played Lois' husband.
An unintentional reference; Enchanted was filmed in New York during the summer of 2006, when Returns was being released.
Except they were. They were extremely popular. Tragically, even the first novel topped the New York Times Best Seller List. Still kind of funny, though.
Nausea Fuel: The "Happy Working Song", especially when the rats are cleaning the toilet with toothbrushes.
Strangled by the Red String: Deconstructed and played straight. The Aesop of the film is that this is impossible... and then it hooks up two characters at the last minute. Hmm.
Possibly justified in that showing that love still takes many paths, although it's an exception rather than the rule in reality as the film cheerfully shows under its premise.
There's also a hint that love works differently in animation. Robert and Giselle may have spent weeks or months getting to know each other, while Nancy is marrying Edward before her phone's battery has completely run out(!)
Well, it is a parody, so the whole last-minute-hooking-up was probably meant to poke fun at how many of the early Disney princesses got Strangled by the Red String.
Trailer Joke Decay: The scene where Edward is run over by bicyclists mid-song is played in a large portion of the promotional media, to the point where the joke had less of a punch when the movie was released in theaters.
