The Girl Who Leaped Through Time have been on my list for a long time, and I finally got a chance to see it. The movie is simply wonderful: fluid animation and rich backgrounds, touching music and lyrics, and, of course, the story. The plot revolves around a high school student who discovers an ability to time travel and learns the blessings and curses associated with that skill. I added this movie to my list of anime recommendations.
Events that happen to us, people we meet, emotions we feel are unique combination of circumstances. The moment when s/he said something to you and the time you spent together may never repeat again. Cherish those moments and think carefully when you act, for your decisions will have a significant impact on the future.
