"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, while their situation seems to establish that nontraditionalists sometimes make great partners.
