* AlternativeCharacterInterpretation / BaseBreaker: Vanessa is either a [[TheWoobie Woobie]] who wants to be a mother or a {{Manipulative B|astard}}itch who doesn't have the emotional fortitude to be a good parent. There's seemingly no gray area; people who see the film are either with her or against her.
* SugarWiki/AwesomeMusic: The soundtrack. The Moldy Peaches' "Anyone Else But You" is now [[SongAssociation inseparable]] from the movie.
* BrainBleach: Oh, GOD. Those [[UnusualEuphemism PORK SWORDS]]!!!
* EsotericHappyEnding: Some viewers have a [[AbusiveParents very dark]] interpretation of Vanessa's future relationship with Juno's son and where it might lead. Though the movie paints her in a sympathetic light for choosing to go ahead with the adoption after Mark leaves, one can't help but wonder how she'll cope with being a single parent while still reeling from her painful split with Mark.
* GeniusBonus: While the movie mentions that Juno's named after the Roman goddess Juno, it doesn't mention that one of the main domains of the goddess is childbirth.
%%* HypeAversion
* NoYay: Mark and Juno, when they dance together.
** Mark and Juno in general. More than one viewer might have thought this movie was about to take a turn into ''much creepier'' adulterous MayDecemberRomance territory with the way Mark kept being so friendly to Juno and the way she kept spending time alone with him, but no, that's not what happens.
* RonTheDeathEater / TheScrappy: Vanessa is subject to this by haters of the film.
