She is quite a bit darker and more sinister than her four-color counterpart. Clint was merely the agent who disobeyed orders to save Natasha's life.
One day I'd like Natasha to get her own film wherein her past can be fully fleshed out. It would be interesting to see her having to deal with the real consequences of her past actions without SHIELD providing her protection.
I don't know. Mysteriousness works well for the Black Widow (her being a spy and all) and we've seen what happens when they take mysterious characters and begin fleshing out their mysterious pasts in full detail... they become less interesting.
