At the center of The Witch is the family's eldest daughter, a young woman named Thomasin (Anya Taylor-Joy), whose coming of age is even more fraught for taking place in a secluded wilderness with only her family around. Her mother seems to suspect her of being untrustworthy even before witches enter the story, and her younger brother keeps sneaking glances down her shift.
I am not sure what the brother exactly does. Does it mean that he is attracted by his sister? Is not in the review a TYPO when "shirt" was mistakenly replaced by "shift"?
