They're my favorite kind of movies!
While You Were Sleeping is my favorite, but I also like Sleepless in Seattle, Return to Me, Under the Tuscan Sun, Sisterhood of the Travelling Pants, 50 First Dates, One Fine Day...I can go on and on...
PRETTY WOMAN by far!!! I can watch that a million times!
Also: Serendipity Sleepless in Seattle Shadowlands (a major tear jerker, I think I need to watch again) Wedding Planner Return to Me (have any of you seen this with David Ducovny and Minnie Driver? Another major tear jerker! Love it!) Somewhere in Time
