This is a wonderful series, one of the best new shows, nay best shows period, that the BBC have ever aired.
This is a terrible DVD "complete" set, one of the very worst lack of efforts they've ever done. The BBC did an astounding job of producing extra material for this show for their website (short features filmed specially for the site showing some of the history of the leads prior to the show, actors filming behind the scenes diaries, etc) and for BBC 3 (the excellent Unearthed documentary and the pilot episode that started the whole thing). And NONE of it is on the "complete" DVD. On top of that, much of the distinctive music from the show which helped set the atmosphere has been replaced with bland stock stuff - come on BBC, nowadays when you strike a deal with a musician or their label to use their music in your TV show, you make sure that deal has the DVD release written in too.
I'm terribly disappointed. I'd have been better off taping the episodes and downloading the features from the website than buying this, because then I'd have a better package than this, and for less money.
