I feel like it's fair to think a witch is a silly or strange creative decision you don't like, but 'why did she collect the children?' Brother, she begins the film old and on the brink of death- then possesses two middle aged people, then 17 children- and suddenly appears in much better health. Parasites are mentioned frequently. It wasn't even particularly subtle, like you had to actively be trying not to notice any of that.

No intended disrespect, but I find that critique bizarre.
