* AudienceAlienatingPremise: What several industry papers chalked this movie's financial disappointment to, despite solid critical reception, a strong comedic pedigree, and desirable release date: the story of a couple being unable to finish tying the knot for five whole years was probably not a winning one in terms of appealing to a wide audience.
* BrokenBase: Viewers seem to be split on Alison Brie's English accent as Suzie. A lot of people criticised it, finding it completely unrealistic. Others however were more favourable to it. It's worth noting that she specifically attempted to imitate Emily Blunt's natural voice - and Emily herself says that her voice is all over the place from her years of working in America. So Suzie's OohMeAccentsSlipping might be deliberate, to show that the sisters have lived in America for a while.
* CrossesTheLineTwice: A toddler causing her aunt to be shot is tragic. When said aunt gets shot in the knee with an arrow from a crossbow that was left on the table - while the toddler excitedly says "I'm Pocahontas!" - is hilarious.
* EndingFatigue: One criticism of the film was that it just ran too long before [[spoiler: Violet and Tom ultimately do get married]].
* SugarWiki/HeartwarmingMoments: [[spoiler: Violet and Tom's eventual wedding at the end of five years, after having put things on hold and endured all manner of setbacks]].
* NarmCharm: Violet and Suzie having an argument where the presence of Suzie's daughter has them speak in Cookie Monster and Elmo's voice respectively. It's about as cringey as you'd expect, and that's why it's funny.
