The reason I don't find Snow White or her voice off-putting is...yes, she's child-like and innocent and sugary, but she's also genuine. She's not being coy or putting on an act. She is what she is. And she's not without a bit of grit or sass. In the movie, when she sees Grumpy glaring at her and says to him, in a deeper voice, "OooOHHHHH... YOU must be GRUMPY!" that just kills me.
