When people don't like your characters

So your book is done, it's published, people are reading it, most of them are liking it (hopefully).

But then somebody hates your character.  Hates.  Abhors.

We'll say it's the heroine, because usually that's who it is for me.  Either she didn't see the bad crap soon enough, or she had too many problems, or she didn't think about all the things going wrong, maybe she didn't take the bad stuff seriously enough or….they just couldn't connect with her.

What then?

Does that mean you did your job...
