Theirry Attard's Double Feature
The reviews seem to be mixed. I'm not surprised. The series is trying to balance a fine line of keeping true to it's predecessor while also trying to be British. And if I recall correctly, the original Law & Order was not the best reviewed series the season it debuted.
I'll try to update this post as the day progresses. If you find any additional reviews, please leave a comment and I'll add your link.
