How about people just stop saying "Sue" since there's a billion different definitions for the term, and half the time you can apply those definitions to time-tested much-beloved characters? It's gotten fucking idiotic. It's gotten BEYOND idiotic. Just say what your problems are with the character instead of using such an utterly worthless label.
You can even say "she's a bad character". We'll all understand what you mean, and in this case I'd agree with you.
