My point of view.
What makes an Anime Identifiable?
Simply the:
1.
Characters
Name one cast like Kenshin links you to Samurai X
2.
Genre
Cannot be relied to but it helps if one is unique to the anime.
3.
Company/Author
Otakus are very familiar with this. Name the
who and you got yourself a list.
4.
Memorable scenes/Unique scenes
Very reliable if specified. Example,
oh he tried to dunk the ball but got he's head hit the board ring.
What makes a Character Identifiable?
1.
Character ( as in characteristic)
Hmmm.. example.... tsundere
2.
Appearance (dress included
Even in real life you do this.
3.
Seiyuus
Self explanatory
