What I Like About You (2003)

When their father is transferred to Japan, 16-year-old Holly moves in with her big sister Valerie in New York City. Valerie is 28, highly organized and used to having her life in order, while Holly is spontaneous, impulsive and anything but tidy. As Holly turns Valerie’s routine upside down, the sisters find out that loving each other as family is one thing, and sharing a home is another.
