This movie's Japanese title is "50回目のファーストキス”. I didn't know real title and I believed that is " 50 first kiss". Japanese is good, but, I like "50 first dates". which title do you like best?
I like the original title. When people are on a first date they usually try very hard to be nice and kind, interesting, and do their best. They want to make a good impression. But as people spend more time together, they become less careful about how they present themselves. They don't always do their best. I think this story tries to tell us that we shoud act like we are on a frist date, even when we have been together or married for many years.
