While You Were Sleeping is a great movie. Charming, funny, great cast.....& not saccharine. Sandra Bullock is delightful.
Also in that category: Family Man, A Walk In The Clouds, Overboard, Sweet Home Alabama, House Sitter, and Frequency. All but Frequency have romance, but its strong affirmation of the importance of family ties far outweighs its status as a crime drama.
Most people consider It's A Wonderful Life as only a "Christmas Movie," but the scene of Jimmy Stewart & Donna Reed sharing the phone receiver is one of the sexiest scenes ever filmed without having to show a lot of bare skin.
