Bored stoner Elfie Hopkins (Jaime Winston) tries to make village life a little more interesting by dabbling in amateur detective work, investigating the lives of other locals with a little help from fellow weed-toker Dylan (Aneurin Barnard). When a sophisticated city family, The Gammons, moves into the house next door, Elfie's investigative nature begins to tell her something isn't quite right with her new neighbours. Digging into their background, she uncovers a horrific secret that puts the lives of her nearest and dearest in mortal danger.
It took me a while to warm to Elfie Hopkins: at first I found the central character rather irritating, Jaime Winston's attempts at cool and quirky seeming just a little too calculated to appeal to the cult movie contingent (her lovable slacker routine reminding me a little of Simon Pegg in Shaun of the Dead). But as the story progressed, the film gradually started to grow on me, Winston's appeal winning through, the whimsical nature of the story and creepy antagonists slowly getting under the skin. By the time all becomes clear for the final act, I actually found myself enjoying proceedings. The finalé is a real crowd-pleaser, Elfie tooling up for a revenge-driven gore-fest that really gets the blood pumping.
To sum up: the film's offbeat and rather relaxed approach makes it hard to get involved, but perseverance pays off, with a particularly fun finish. A sequel with Elfie investigating even more outlandish situations wouldn't be entirely unwelcome. 6/10, although a repeat viewing might see me bump my rating up to 7.
