In Digimon: The Movie, time is seen as a challenge in many ways. The first conflict of the movie occurs as Agumon and Parrotmon begin to fight in the city, causing widespread destruction. This occurs, of course, in the middle of the night, so only a few people witness the event. The second conflict with Diaboromon gains a deadline when he takes control of the internet and gains access to devastating missiles in the real world. The third conflict involves a boy Willis and his corrupted digimon, Kokomon. The eerie repetition of "Go back ... to the beginning" is the third major reference to time in this movie.
There were a couple of other anime movies that dealt with time and the consequences of growing older and growing apart. A number of these are directed by Makoto Shinkai. These films include 5 Centimeters per Second, Voices From a Distant Star, The Place Promised in Our Early Days, and Children Who Chase Lost Voices. These 4 films are all very moving, and the main characters struggle with different aspects of growing up and growing apart.
|5 Centimeters Per Second: A Chain of Short Stories About their Distance|
|Voices of a Distant Star|
These two movies explore the challenges that time and distance can create in maintaining a relationship. The other two movies are also fantastic (but I don't remember the plot, just that I really liked them). What I do remember is that all four of these movies tell the story of someone who is trying to reconcile the future they always thought they would have with the future they are starting to live, and struggling to make it into the future they desire.
