Very Bergman-esque
Reminded me a lot of Hour of the Wolf as well as Shame (even the Virgin Spring).
Fantastic atmosphere and ceepy tone throughout.
I also liked the ambiguity; the fact that she could have been a witch from the start (hence their banishing) or that could have been pure coincidence and she's recruited after this. Then of course there's the possibility that she isnt a eitch at all and has just eaten some poisonous corn and hallucinated her way through murdering her entire family.
Not a perfect movie but very good.
