I have just finished watching series 5 half expecting the standard to have dropped from the five star entertainment provided in the first four series, but no, messrs Armstrong, Bolem, Waterman et al... just keep getting better. Every episode is a different story, but all are superbly written, acted and directed. I just love the blend of comedy, drama, mystery and action. The chemistry between ALL the components of this wonderful series is evident in the finished product. I just hope that this standard of entertainment can continue into Series 6 which is not due for release on DVD until autumn 2010. I just cannot recommend highly enough.
