10. Seven Brides For Seven Brothers
They say you always kidnap the ones you love. Wait, nobody says that, and for good reason. Seven Brides For Seven Brothers may be a cheery musical with impressive dance numbers about the bygone days of 1850s Oregon, but it gets dark quickly. The eldest of the titular brothers quickly talks himself into a wife (after singing about how the other women in town are either taken or don’t meet his physical requirements), then persuades the rest of his brothers to do as the Romans did. So they go into town at night and kidnap their love interests, who are initially angry and frightened, but end up forgiving their captors and falling in love with them. Everyone ends up reconciling and marrying, which seems like a clear case of Stockholm Syndrome with all seven couples, none of whom should be together.
