Despite this being the fifth series of NX, there are no signs of contempt or staleness creeping in. This marvellous series continues to charm us with excellent and unusual plotlines, brilliant acting and breathtaking scenery. If you're a fan, then you'll already know this, if you aren't, I suggest that you shell out a tenner for series one, then collect them all in sequence.
I for one can't wait to add series six to my collection as well. This is the only show I've gone to such lengths to watch again so many years after it was originally aired. It hasn't dated a single bit, I'm elated that they've all been released to DVD.
