Brash, handsome, sullen and a total know-it-all. Anakin is devastatingly charming when he wants to be, but seems to have a big chip on his shoulder the rest of the time.
There is a lot of Anakin bashing regarding the prequels, but I think most of it is unfair. If you think about it, Anakin behaves pretty much like any normal teenagers (he was about 19 in Attack of the Clones). He struggles with insecurity, while at the same time he acts like he is infallible and invincible. He knows he has this amazing ability, but like most kids, does not have a clue how to appropriately use his talent.
