French crime drama 'Witnesses' appears to take many of its cues from the superb Danish series 'The Killing': an intense, career focused, thoughtful but lonely female protagonist, with a tendency to go into dark places alone, coupled with a landscape that is always painted grey (in this case, the seaside town of Le Treport, which probably won't attract too many additional holiday makers as a result of its portrayal). Unfortuantly, there are also some problems, most notably, a complex plot that doesn't make a lot of sense. For example, it's clear that the crime under investigation involves someone seeking revenge on a retired detective, so the first thing the police do is to bring the person in question back onto the job specifically to lead the case. It's a standard trope of television detectives, of course, that they accidentally find a personal link to the case they're investigating; but it's a bit crazy to assume the reverse, that a known personal involvement would lead to someone being put in charge, especially as much of the tension in the drama comes from his own reluctance to share what he knows with his colleagues. The acting from the two leads was good, and I also liked the mood of the piece, but ultimately, the story just isn't very plausible or engaging.
