I love sci-fi and horror films and this checks both boxes. The story is about 3 sisters who are chased and threatened by a scary halloween spirit that seems to haunt the island from which they came. They fight this demon the best they can while people, including their aunt, die all around them. I won't give the end away, but it's an interesting movie with a rather predictable progression. The ending, however; is a bit of a surprise. Not for children under the age of 13.
