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: Five Hundred Days Of Summer
Award Snub: No Best Original Screenplay nomination?
Better on DVD: The brilliant use of Anachronic Order can be more easily appreciated if you can rewind and rewatch scenes and transitions.
Big Lipped Alligator Moment: The spontaneous dance sequence (the morning after Tom and Summer have sex for the first time), which is simultaneously a glorious movie musical dance scene and a hilarious parody of movie musical dance scenes.
Fan Dumb: Zooey Deschanel was quite taken aback by the volume and vitriol of the hate mail she received in response to "her" alleged mistreatment of Tom.
Tear Jerker: The "Expectations vs Reality" Party scene is a real kicker though, esp. for anyone who has had a similar experience.
As is the last scene at Tom's spot in the park.
This troper was pretty torn up when the BookEnds conversation from Day 488 was revealed to be an echo of an earlier conversation.
The Woobie: Tom's misunderstanding of Summer and their relationship is his fault; but it's never out of maliciousness, and he does genuinely care for her, and it's hard not to feel sorry for the guy.
