"You're the Worst" isn't a typical romantic comedy. Narcissist Jimmy Shive-Overly thinks all relationships are doomed from the start, while stubborn cynic Gretchen Cutler is certain that amorous bonds aren't her thing. When the two meet at a wedding, though, there's a sea change: They go home together and find they're beginning to fall for each other. Jimmy and Gretchen navigate fear, heartbreak, ardor and other feelings, and their situation seems to establish that nontraditionalists sometimes make great partners -- but not forever. They eventually break up and become involved with other people, leading them to struggle to move on while being pulled back toward each other.
