Itachi thinks she's nice. He already sort of had an impression of her because Sasuke has shared memories of her and he has remembered part of the fight from the Gaara arc and remembers her being there for that (though he was fighting Kakashi, so his impression from that isn't that big). He knows from Sasuke's memories that she's smart and that she was in love with Sasuke. He's not really sure how the latter thing is going to play out, but she doesn't remember Sasuke at all now so there's nothing to do but wait and see.

But so far she seems pleasant enough and determined in a more shounen way than he necessarily would have expected, but he doesn't really see that as a bad thing. At least not as long as she's careful about going out at dawn and dusk. Though he didn't actually judge her too hard for that. Mistakes happen, and he can understand going after a teammate who's in danger. He just knew Sasuke would be upset, because he also knows that Sasuke cares about her, even if he tries to pretend that he doesn't. And he does think it's good that Sasuke has people he cares about around. So he will probably keep an eye on her. Though at some point he might warn her that any memories she might get of him will be unpleasant. He won't go into detail, because she hasn't expressed any interest in being told about memories. But just. Fair warning.

Does Sakura have opinions or impressions of any other teams besides Turquoise?
