* AlternativeCharacterInterpretation / BaseBreaker: Vanessa is either a [[TheWoobie Woobie]] who wants to be a mother or a [[LeeroyJenkins reckless]], [[ItsAllAboutMe self-centered]] {{Jerkass}} who doesn't have the emotional fortitude or the know-how to do so. 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. Let's not forget that she still has a very demanding job that will eat up any time she intends to spend with the child.
* 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.
* HilariousInHindsight: After Ellen Page came out, it is ironic that Juno suggested giving the baby to "a couple of nice lesbos"
%%* HypeAversion
* LoveItOrHateIt: Less the movie so much as the dialogue. It's quirkiness is either a huge part of it's charm or deeply obnoxious.
* MisaimedFandom: Not by a whole lot, but pregnancy fetishists have a great admiration for this movie, especially the scene in which Juno enthusiastically rolls up her shirt for Vanessa at the mall.
** And then there's those that use the film as a tool to promote pro-life or pro-choice arguments with regards to abortion, when WordOfGod indicates that the film was meant to be neutral on the subject.
* 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.
