What do spiderman fans think about teresa. Do they like her introduction or no?

So I've recently just found out peter has a sister but I'm not sure if it's still canon. But after finding her out, I began searching more information about her but I've also stumbled upon people's view on her. Some are positive and others negative. I saw one comment referring her as a "self interest character" or something more positive about her.

Is she a liked character or not?
