* CrazyAwesome: Megan
* EnsembleDarkhorse: Megan. Melissa [=McCarthy=] was nominated for an Oscar for Best Supporting Actress for a reason.
* GirlShowGhetto: General consensus is that this was averted.
* JerkassWoobie: Annie
* {{Moe}}: Becca. But seeing as she's played by [[Series/TheOfficeUS Ellie Kemper]], this should be expected.
* OneSceneWonder:
** Lillian's dad is in both of his scenes.
** Annie's CrazyAwesome mother as well.
** Annie's roomates count as well.
* {{Squick}}: The scene in the bridal shop.
** Also Megan and Air Marshal John's sex scene.
* UnintentionallyUnsympathetic: Helen's reveal of her own problems and insecurities to make the audience see she isn't the AlphaBitch Annie sees her as can fall flat when one looks back at the rest of the film and realizes how often she's gone out of her way to upstage and embarrass Annie.
* UnsympatheticComedyProtagonist: Even though most of what's happening to Annie isn't her fault, some of her reactions just make her look like a jerk, including her behaviour towards Rhodes.
