10 Things I Hate About You (1999) The situation: Bianca can't date unless her sister Kat does -- and Kat hates all guys. But that changes when Heath Ledger wins her heart with karaoke, a guitar and his sweet Australian accent. The lesson: Even angry feminists can fall in love. Best for: Fans of the Bard. The movie is based on Shakespeare's "The Taming of the Shrew."
