Watched both series of Nashville recently on Sky Box Sets, and thoroughly enjoyable it was too. Have to say that to be able to download a whole series at once, with no adverts, is worth the Sky Subscription alone!
We watched at least three (3) episodes a day, which at 40 mins or so each is like a movie, often more as it was a tad addictive (and I have even started listening to some Country music on our Pet Transports between Spain and the UK).
They are making a third season which is great but …… do we watch it as they air or store them up and watch them in ‘one hit’. Generally we store things like this up and watch in one hit i.e. where there is an ongoing story line, and tend to only watch programs as they air when they aren’t building a story line.
