Elfie Hopkins (Jaime Winstone) is a young woman with too much time on her hands as when she isn't strolling around the local woods, or getting baked with her friend Dylan (Aneurin Barnard) she is coming up with stories about the people in the village as she thinks of herself as a bit of a detective, a British Nancy Drew. But things take a turn for the curious when the Gammons move in nearby as they talk of exotic hunting holidays and entice locals to book holidays with them as whilst the locals disappear they don't go on holiday.
I reckon a better title for "Elfie Hopkins" would be "Nancy Drew Too Hard" as this is one odd ball British horror movie which keeps you watching not so much because it is entertaining or engaging on an intellectual level but because it is so friggin' odd-ball you wonder where it will lead. From the way Jaime Winstone looks as Elfie to the way the Gammons act like posh totty it is like a group of people sat in a room and wrote their own individual versions of a story and then they mix and matched elements to create this oddity.
The trouble with "Elfie Hopkins" is once you get past the initial novelty factor of its odd-ball elements it offers up very little. From Dylan having always been sweet on Elfie to the whole murders and missing people in a small village there is nothing fantastically new going on and to be brutal it quickly becomes tedious as you want for something interesting to happen. It does eventually but you have to sit through what feels like a lot of thriller to get to it.
What this all boils down to is that the character of Elfie Hopkins is entertaining but the movie "Elfie Hopkins" isn't and it is a case that once the novelty odd ball nature of the movie wears off it doesn't have anything to replace it other than more odd-ball stuff.
