I recently watched My Sassy Girl (http://www.imdb.com/title/tt0293715/) and I loved it, really I haven't seen any romantic comedy like it: I don't like harsh romantic comedies, but this one was perfect, it made me laugh a lot, and was romantic: I loved the story and I'm looking for similar movies: any hints? Thanks!
Windstruck ( 2004 ) Jae-young Kwak http://www.imdb.com/title/tt0409072/
is rather similar in style, but I liked it better, it's IMO less over-the-top, but the majority prefers My Sassy Girl.
In comparison to my "lists and recommendation" answer I now selected especially those films which include a love story.
