One of Mrs. Salad's picks. She's from the scene of the crime itself, Fall River, Massachusetts. Although it happened well before she was born (good alibi, honey!) and in a swankier part of town than hers. The movie's R rating is due to "violence and grisly images, nudity, a scene of sexuality and some language."
In case you haven't guessed, it's a retelling of the Lizzie Borden story. Which you probably know: Lizzie's father and stepmom axed to death, Lizzie acquitted at trial, no charges brought against anyone else.
So there's room for a considerable amount of theorizing as to the culprit, motive, and methods. One hint from the cast list: starlet Kristen Stewart plays the maid, Bridget, so it's safe to assume she's a major part of the yarn. Which, in this version is pretty sordid, and not complimentary to anyone involved.
It's kind of boring at the beginning, setting up the characters and their mostly toxic interactions. Lizzie and Bridget give each other a lot of hot, lingering, open-mouthed stares. ("OK, we get it!")
