I always expect the worst when I will see a romantic comedy. It's all very much the same, ultra sweet and incredibly predictable. One Fine Day does confirm this, however it isn't as bad as most of the movies in the genre. It's actually a quite enjoyable and funny film.
Michelle Pfeiffer and George Clooney did a very good job playing two people who are divorced, with a child, afraid to commit to someone else and with a hectic life. One day, they accidentally meet at the school where their kids go to school and during the day they keep meeting, however they hate each other and don't want to see the other ever again. But as the movie progresses, the relationship between the two changes from hating each other, to liking, to ... (this is a romantic comedy, I don't have to explain everything I hope).
Even though some parts aren't excellent, the entire movie is actually quite good and enjoyable. It shows a lot of stereotypes of course like the ex-husband who doesn't want to help his ex-wife when she drowns in all the work and who needs him to take care of the kid, the man who still seems to act like a little child... But when you can see past that, it's an excellent movie to watch together with your wife or girlfriend. You'll both enjoy it. I give it a 7/10.
