Stregheria Horror Film?

Among the random things in my news feed today was a trailer for a new horror film: “Trick of the Witch”. In the accompanying text it said the film was based on Stregheria. While all the trailer really reveals is a low-budget horror flick that’s short on substance and style, there are approximately 590 hits when you Google the name of the movie with “Stregheria”.

So I’d love to hear from folks who practice Stregheria on their take on this: Is it an opportunity to educate, or a film best forgotten?
