Marmee was all wrong
Sarandon just had to put her ego and politics all over this, didn't she? Marmee was a very conservative, devout lady. She didn't go off about corsets and girls being allowed to romp around. She was very proper. As Jo once pointed out, if they were running away from an earthquake, she would still probably say "Girls, girls... have you both got clean pocket handkerchiefs??"
She was the one who said the sweetest, best thing that could happen to a woman was to be chosen by a good man. Now I'm not saying she was right, but if you're going to remake an old classic, it's just arrogant and stupid to take this kind of character and decide she's gonna be the editor of Ms. Magazine now.
This 20th century femi-mommy made no sense in this story. But Sarandon can't vanish into a role like Meryl Streep or Sophie Thompson. No, she's gotta make the role vanish into her.
