A lot of stage productions portray her as the villain of the piece while her husband is an ineffectual cuckold almost, doing her bidding to disastrous ends. Some classic Shakespearean studies list her as an example of Shakespeare's ambivalence toward female characters in general. I think one of my professors tried to make that case.
I don't necessarily agree, I've always thought Shakespeare's female characters were richly made and whole, right down to failings, dark sides and baser instincts, a concept sometimes lost on modern writers and audiences.
But then, you were asking cakewalk lol. I'll just be over here in the corner.
