There also seems to be an underlying theme in the film that magic is entirely illusionary and that doesn't sit well with me. Magic can affect permanent change as much as anything else.
And what a confusion between Witchcraft and Wicca in the film. Those little madams were most definitely not Wiccans given some of the naughty spells they were getting up to, but their constant “Blessed Bes” were not in keeping with a more traditional bent. All in all, the research team could probably have worked a bit harder. Good film though.
