One specific issue for me was disrespect toward Data (mispronouncing his name even after he corrects her really irked me). He was an officer and he should have been treated accordingly.
But that didn't really last beyond...what, her first three episodes? I'd agree that during The Child and Where Silence Has Lease, she doesn't treat him all that well, but in Elementary Dear Data her criticism of him is kind of justifiable. After that I remember more Pulaski/Data moments where she was being nice
to him than being disrespectful. Moments such as
- Attending his farewell party in Measure of a Man.
- Grateful for his support as she deteriorates during Unnatural Selection.
- Cheering him on Peak Performance.
- Being the only
person to tell him that he did the right thing in Pen Pals.
