We've known Martin Shaw from other British TV productions, e.g., P.D. James, and he is good. This made it a potentially worthwhile purchase. We weren't wrong and the DVD even has subtitles. The whole production is excellent and we've preordered Series two.
For those of you who read this who live in Region 1 (NTSC) let me encourage you to buy a multi-region DVD player - Amazon U.S. has them - so you can enjoy these Region 2 (PAL) DVDs some of which are only available at Amazon UK. You may even find that the costs of buying them from Amazon UK and having them shipped to your US address via Royal Mail is cheaper than buying them in the US.
