Daniel Vernon provides portraits of extraordinary sensitivity and clarity.
 
John Lloyd, Financial Times
Daniel Vernon’s film is some sort of frightening sub-species of masterpiece which plunges you into a claustrophobic world where duty, ill-temper, sacrifice and insanity grind together like bone on bone.
 
The Times
Ostensibly a portrait of British eccentricity, this is really about the way in which family members develop co-dependence, and it is strongly reminiscent of the Maysles Brother’s 1975 masterpiece on the parent-child situation, Grey Gardens.
 
The Guardian
It was shot like a glossy Nordic-noir drama, all brooding grey skies, rain lashing over windscreen. Thankfully the high-end look was not to make the police look better, or trick you into thinking you were watching the latest box-set hit. Instead, this fictionalised styling made the horrifying reality of the murders even more intense.

With hand-held cameras, moody music and clever editing, The Detectives was intimate and immersive. I found myself rooting for the police even more than I do with fictional crime dramas.

Few films have captured so vividly the desperation of loneliness.
 
David Chater, The Times
In the circumstances many film-makers might have been tempted to go for some metropolitan sneering of bafflement. Here, though, Daniel Vernon provided a warmly sympathetic portrait of a form of English life that apparently hasn’t disappeared after all.
 
James Walton, The Daily Telegraph
The level of contact the film-makers get is access all areas. Sometimes it’s routine, at other moments it’s uncomfortable; but it’s always fascinating. 
 
Sam Wollaston, The Guardian 
A touching, moving, funny sad whimsical film, which had the added bonus of being gorgeous to look at. It also said something rather profound about masculinity and loneliness.
 
Kathryn Flett, The Observer
Beautifully shot, startling characters and as wonderfully odd as only our muddled little corner of the island can be.
Joe Nawaz, The Telegrap
Wonderland's The 92-Year-Old Danger Junkie is the latest in an emerging documentary strand of reliably wonderful eccentricity. A superb and haunting programme. 
Hermione Eyre, The Independent 
This was a lovely documentary, but it was not really documentary at all. It was like a short story about a character and a relationship. Daniel Vernon’s delicious film asked the right questions.
