The Five-Year Engagement is a middle-of-the-road modern-day romantic comedy. The movie starts with Tom (Segel) botching his proposal to Violet (Blunt) one year after they first met, then continues on for the next five years as their wedding gets further and further postponed for various reasons. Things crop up in their lives and they start to doubt that they really are perfect for each other. It has its fair share of quirky side characters, some of whom you love (Kaling, Hart, Posehn) and some of whom you love to hate (Pratt, Ifans). It's got the big fight in the middle--although it does it in a way that makes both leads less likeable--and a terrifically sappy ending to jerk some tears out of your nasolacrimal ducts. The humor is occasionally raunchy to give manly men laughs but is usually simple and clean for the more mainstream viewers. It's formula to a T, and it's entertaining enough. It just isn't exciting enough.
