well lets see y iz sailor moon a classic its i think the main criteriaEverybody. What are you doing? Hope good things. . .
Ok, to the point. Reading about classic anime series i can't to identify the elements about that anime is a classic. Some series have a lot of chapters (Dagron Ball, Macross) and another don't (Evangelion). Some series have funny elements and another sad elements. The time is another variable. Is the time one of the elements?
On my opinion i think the characters is one of the elements. Why? The main character is the "movil" of the story and make an anime fun or bored. Of course, with the help of the second characters. An anime without lovely main characters don't have that "feeling". Haruhi Suzumiya Melancholy or Cards Captor Sakura have main characters with "angel" and both are great animes. And both are "recent" series.
What do you think? What elements do you think one anime must have to evolve on a classic anime? The time is one of them or not? An anime with 5 years can be a classic or need wait 15 years to win the tittle?
I wait for your replies.
