I bought this on special purely based on the reviews it received on MA and the net in general (i.e. I knew absolutely nothing about the series before buying it).
The series itself is actually really well produced. Both the actors (in their respective roles) and the locations are depicted in a way that really draws you into the relevant worlds created.
As for the quality – well anyone who has enjoyed high quality full HD/bluray will not be dissapointed. Both visuals and sound are top-notch, and essentially create the foundation for believable watching.
Would definately recommend to anyone who want to throw away a few hours in front of the box :)
