From the information posted on IMDb's site I gather this is an opera prima and if so, we might be in presence of a talent to reckon with. The interview with the director included in the DVD clearly shows a person in his twenties, ready to show what he learnt and is capable of.
Yes, the first half hour or so is confusing -maybe deliberately so- but I'd say the plot is cleverly exposed and handled. And the way things turn out to be and how the particular murder the film begins with fits into the series of killings the plot centres on is smartly devised. I concur with others, commenting the movie on this website, on the unresolved issue of the neighbour mum and daughter, perhaps a more seasoned film maker would have taken care of that more adroitly; yet a case could me made towards the transposition of the detective's wife and unborn child and hence the attention he gives these otherwise peripheral characters. Criticising slowness in plot progress in European films is common in this side of the Atlantic and it's really no big deal. They make their films evolve at a given pace, US and (some) Latin American film makers prefer a different one, it's a question of personal preference.
But in sum, let's follow the work of this young Englishman, for he seems a promising talent.
