Okay, I LOVE romantic comedies so this is probably not too objective but... gee, I loved this movie. It follows an old formula that has worked so many times and that is still working: 2 people who can't stand each other at first happen to spend some time together and eventually find each other attractive. This requires 2 main things: 1.) Two great actors with wonderful chemistry 2.) An original and funny script We have seen this in so many movies like 6 Days 7 Nights with Anne Heche and Harrison Ford or You've Got Mail with Tom Hanks and Meg Ryan or recently in The Runaway Bride with Julia Roberts and Richard Gere. I loved all these movies for they simply worked to charme me. One Fine Day fits perfectly to this list. George Clooney ( who proves that he can be a very funny guy) and Michelle Pfeiffer ( who gives a great performance in this movie) have very good chemistry and the script is very funny and romantic with some really great one-liners. This movie entertained me very much and it wasn't boring as I saw it the second time. For it's charme and fun, I give this movie 9/10.
