Wow. A great summer holiday would be to watch all nine seasons of this great series non-stop and for the first time. All other crime dramas pale in comparison. It is what Cold Case and the CSI series want to be when they grow up, get better writing, less commercials, etc. I started watching this series way back when it showed in the States on BBC America. Unfortunately it only showed for a couple seasons but was available for rental. Then--unfortunately again--the more recent series (after 2005) never seemed to be available and so it wasn't until 2007 and I was forced to buy a region free DVD player to watch another British drama series (Bad Girls) that I finally ordered the series from Amazon. Every year I'd eagerly await the arrival of the new season and every year I buy it and try to "ration" my viewing so that I didn't see all of the episodes over one night. Very tough to do.
The writing, acting and interplay between all of the cast members are exemplary. The story and plot lines are both fascinating and compelling. Even as cast members left (Amelia and the first forensic scientist Frankie) and were replaced by new members the level of acting and the plots remained superb.
The interplay between the Trevor Eve and Sue Johnstone characters alone was far superior to most of the inane banter between characters on other shows. If you haven't seen this series or only have seen a couple of the episodes get it and watch them. You won't be sorry!!
