GreatestSin wrote: i think there is actually a reason why uchihas got so much exposition: A few key characters are Uchiha, and the three last defining moments were all Uchiha-related. Valley of the End, Kurama attack and Uchiha Massacre all involved Uchiha. Even the most recent event alone, the Massacre, was a hugely defining moment for Konoha. Sasuke is also an Uchiha.

So it's not that weird that the Uchiha get a lot of story. But also note that unlike other characters, the Uchiha are more defined by their clan than anyone else, as the Sannin for example were barely even attached to the village. So it's vastly exaggerated by the fact that most other characters had other stories than their clan, and the whole idea of being defined by a clan was rapidly dying out.
