Nodoka is cynic, antisocial, genius type of character like Dr. House or Sherlock from that overrated show.
Difference between them is nodoka is not the main character. We don't see her issues and struggles in the spotlight like Dr. House. We can't feel bad for her, we can't sympathize with her, we can't cheer for her when she succeds like when Dr. House saves the day or the patient.
When she disregards feelings of other people no one can defend her like they can defend House or Sherlock. ("Yeah, he is a dick but he saves lives and he was right from the start".)
With Nodoka, almost all of her actions had no justification or accomplishment which made her a badly writtten villain.
Only a last couple chapters that we are seeing the fruits of her labor. From childhood, she had to take care of a crazy mother that she suspect she "is not crazy, just scared", in a world full of meaningless toys she can break infinitly and always come back anew.
Now sensei remembers to keep Nodoka from resets, we will see her real character.
