Great show... shame about the extras
Can't fault the show itself.... well acted, directed and great music. The extras (which amount to one feature on Disc 5) are atrocious. What you get is a basic recap in 35 minutes of the 21 episodes you've just watched.
Even the US release has a tour of Nashville (with the actors on a trip to the locations used in filming) and a couple of commentaries.
Perhaps wait for the Blu-Ray (though there's no release date slated), invest in the US version or wait for the inevitable 'Special Edition' with the US extras on.
4.5 stars for the show. 0.5 stars for the extras
