I’m going out on a limb here: It was unbearably tedious. The format is ambitious, but so very slow-moving. It simply didn’t draw me in – and the ever-present ‘introductions’ to each piece of correspondence (date, to from, etc) is time consuming and distracting. Get to it, already!
The narration – in particular the main character – is so slow, that I played it at 1.5. And then I stopped playing it altogether. Didn’t give a brass farthing about any of them, and have a life to live.
