* 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.
* HarsherinHindsight: Imagine how Bill Cozby must be feeling post-2014.
* 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.
** This can be read as (partly) intentional, however, since we're not exactly supposed to support Helen's actions throughout the movie either; the revelation simply suggests that the situation is more complicated than Helen simply being a typical one-dimensional AlphaBitch trying to upstage Annie out of pure spite, that Annie isn't the only one who has her own problems and issues to address, and that neither of them have been going about trying to solve those problems in the best or right way.
