In indie horror’s digital DIY era of today, everyone who wants to make a horror movie can and does. This floods the market with dreck — and because even dreck has a minute’s worth of good parts to craft an appealing-enough trailer and inspire an eyeball-grabbing cover — the market is rewarded with rental dollars from viewers left wanting. They’re Outside offers the opposite experience: File the trailer and poster art under “no great shakes,” but the movie itself is that increasingly elusive, rough-’round-the-edges gem.

Combining folk horror with found footage, the UK film follows pompous YouTube psychologist Max Spencer (Tom Wheatley, Piglet’s Big Movie) and camera-operating girlfriend (Nicole Miners) as they shoot an episode on agoraphobia. This primarily entails traveling to the middle of the woods, where former nursing student Sarah Sanders (Christine Randall, Evil Bong 3: The Wrath of Bong) has lived in a little house — and only inside it — for years and years. She’s so terrified to take one step past the threshold, Max assigns himself a 10-day challenge to change that.

Why so scared, Sarah? It all has to do with “Green Eyes” – not the Civil War legend, but folklore nonetheless. As a prologue explains, Green Eyes is rumored to have abducted a child, resulting in a parental mob burning his home, Freddy Krueger-style. As the story goes, he lives in the woods and is identifiable by his wooden mask, cape of leaves and, yes, vacant emerald orbs. Look, glowing eyes in the dark of night is the cheapest kind of scare to make … and when done correctly, as co-directors Sam Casserly and Airell Anthony Hayles have here, ridiculously effective.

Ideally, They’re Outside’s opening card wouldn’t dole out the fate of each main character, but that’s the way of the found-footage film; ultimately, knowing the end does little to hamper enjoyment of the trip there, thanks to Wheatley and Randall’s respective grasps on performing priggish and peevish. For a first feature, Casserly and Hayles do more things right than most, from using subliminal imagery for an extra jolt of creeps to casting Nicholas Vince, Hellraiser’s chattering Cenobite, to deliver the backstory in film-within-a-film exposition. It would be easy to overpraise the movie — and I may have — but these days, “just fine” can be all we ask. —Rod Lott
