Luckily I had recorded 3 episodes of this before watching because I'm not sure I would have bothered watching any further episodes after the 1st one. There seems to be a tendency for new crime series to follow the Scandinavian style in series such as Borgen and I don't have a problem with this especially in Jo. As with all good detectives the main character is flawed, they wouldn't be so good at their job if they weren't I guess. The cast is great particularly Jean Reno and Tom Austen, the Morse and Lewis of Paris.
So why have I only given it 7 stars? Well, it's a slow-burner for a start. I've just seen episode 3 and am enjoying it more as the series progresses. However, I'm not invested in any of the main characters. Jo himself has a troubled past and a tumultuous relationship with his daughter who also has problems, but so far I don't really care. Secondly, this is a series set in France with mainly British actors, good British actors, and yet, they are all adopting American accents. I don't know why unless this is because the producers didn't think an American audience would understand the British accent. Ironically, of course, Jean Reno speaks with a thick French accent and he doesn't compromise that here. If there is to be another series please, please drop the fake American accents because it is needless and annoying and might be the thing that will make me and other, switch off.
