Tight thriller becomes a bit loose toward the end.
POSSIBLE SPOILERS: I thought "The Witches" was a rather nicely paced, tight thriller that fell apart a bit at the end. I feel it slid a bit downhill after Joan Fontaine's character returned to the school after her stay in a nursing home. It seemed almost all of the mystery was then revealed in a premature manner. I also feel The sacrificial ceremony was too silly to be seen as menacing.
Joan Fontaine gave a very good performance. The film features good performances and good production values.
