When Harry Met Sally (1989)
Harry and Sally have known each other for years, and are very good friends, but they fear sex would ruin the friendship.
They just do not make romantic comedies like this anymore. Love this movie and enjoy it every time I watch it.
Harry and Sally meet each other, don’t really like each other, then meet again years later. Second time around they tolerate each other, still go their separate ways. It’s not until like eleven years after the initial meet that they become friends. Their friendship is so genuine and sweet that you could almost end the movie there, but it continues and they fall in love and they deal with the issues that arise.
