She has her points as a supporting character around him.

The version in TAS wouldn't have deserved it, really.
She's deluded and zany, as opposed to being a violent sociopathic sycophant to an even more violent sociopath like she is in some places.
The fact that she settles down and is mostly inoffensive for decades absent the Joker confirms this opinion whatever the motive was.
