I need some romantic comedy films to watch...

here is my criteria, sorry i'm a bit picky...

Has to have a happy ending
Has to be REALLY good in your opinion
Can't be really really old
Preferably something like 2 people's hate turning to 愛 または an impossible situation
Has to make あなた feel all warm and fuzzy, または crack あなた up laughing...

Here are some i've watched recently...

The Proposal
Never been kissed
Confessions of a Shopaholic

etc

Thanx!!
