This is such an amazing piece of work; put in the shoes of someone who loses his sight, halfway through his lifetime, which is one of my personal worst nightmares, I was in tears throughout most of this film. Sight is so essential to my every being, I cannot describe how awful it felt to me, to put myself in the shoes of someone losing perhaps the most important sense of all. It was absolutely devastating to be brought along this journey into nothingness with this film. And yet, as John puts it, it's still a gift bestowed upon him, just like this film is. The whole is so beautifully, atmospherically put together. The cinematography matches the subject so incredibly well, it works with how you could possibly show a person's story who can't see. For a person to overcome this disability, to make the most of it, to thrive on it, despite relying on all senses but his sight, is so amazingly inspirational. I found myself challenging myself to experience my senses, other than my sight more fully. I walked around my house with my eyes shut, I stood outside listening to the rain falling, I familiarised myself to my surroundings. No film to date has ever had this effect on me.

This is a strange and powerful film. It's basically a documentary, with the parts of the people involved portrayed on screen by actors, lip-synching the real life words of the participants. It makes for an other-worldly experience, that's gives a deep insight in to the at once familiar but also utterly alien the main protagonist is forced to inhabit.

The film relates the experiences of John Hull, a writer and theologian who found himself losing his sight just before the birth of his first child. To make sense of his experiences he taped his thoughts - first, reflections on the more practical part of his experiences. As someone who needed to read for his work, for example, he went searching for audiobooks of the academic texts he needed. He discovered that it was assumed that 'blind people don't read big books'; so with an army of friends and families, a library of his books was committed to tape.

As time passes he discovers he needs to understand the condition itself, not just the practicalities of it; he'd found himself so busy preparing for and learning to live with blindness that it prevented him for understanding it. He had to learn to think about his condition: 'If I didn't understand, it would defeat me'.

So begins a series of profound reflections which, as a person who has lived with chronic pain for 20 years, I find very resonant and truthful. The person offering a miracle cure (hypnotherapy) who can't accept John's insistence that his eyes won't just grow back; the people who say he doesn't want his sight back because he seems to have adjusted to it. If we complain about our condition, we're classified as defeatist moaners; if we accept it (as we have to),we've given up (especially as Christians). Onlookers seem only to have categories for the heroic overcomer or pathetic victim; there's no room for someone to keep on, keeping on.

The reflection that 'everyday I wake up, I've lost my sight again'; a painfully truthful expression of the reality that every day I wake up, I'm in pain again.

The reflection on why bad things happen to Christians - 'why shouldn't they happen to me?'; a line I've used myself. This struggle seems to be a bigger one for the people around us, then for the sufferers ourselves. As he says 'I don't regard faith as a shield against the normal ups and downs of life'.

His child screams; they rush to discover it's a finger trapped in a door, but even so he's impotent. "The discovery that you're useless is not a nice discovery for a father to make'; how true. I lie some days in pain, aware of my enforced physical absence from my children and my apparent uselessness as a result.

There are many more moments to reflect on, but the surreal and moving conclusion is the most weighty, as John's dreams are shown melting in to on-screen reality. He ends at a point where blindness (chronic illness) either enables in the sufferer some kind of rebirth, or it destroys you. As he says this, him and his family are soaked in rain, a symbolic baptism and regeneration. It's truthful, healing and challenging all at once.

A unique and wonderful film, to be lived with and drunk deep from - especially for chronic illness sufferers and those who travel with them.

At the beginning of this film onscreen text informs you that John Hull went blind in the 80s and subsequently kept an audio diary. Those original recordings are now used in the film and the actors lip sync to them... It's a beautiful idea and instantly grabs you in this really personal and at times heartbreaking story. Ultimately though, this is expertly crafted and awe-inspiring. It's a theological study as much as a practical one, but John's resolve really leaves you wondering how you'd cope yourself, if you could be as strong. Going blind is a scary thought, but John Hull proves without doubt it need not be.
