What makes this series work is a combination of good writing and acting. The way the scripts have been worked everything that happens seems completely plausible. From the journey our archeologists go on in their quest to discover the sword's whereabouts to how they come across the various clues over the series which helps them solve the ultimate mystery. While it might seem like a string of coincidences that five seemingly unrelated archeological digs should have something in common, the writers have come up with very plausible reasons how each of them connect to the sword.
Complimenting this is the fact each of the actors have created wonderfully believable characters. From Bonneville's wise fool Dr. Parton, Graham's driven Magwilde, Lester's loyal and stolid Ergha to Mbatha-Raw's slightly wide-eyed but never naive Davis, each of them could have easily been types instead of real people. Thankfully both the script and the actors worked together to make them multidimensional people with both flaws and strengths. Over the six episodes we find out just as much about the characters through the actor's performances as we do through the script as they show us as many sides of their character as possible.
Bonekickers comes in a three DVD set with each disc containing not only two episodes, but extensive special features on each episode. In fact there's over 100 minutes of special features which look at script creation, special effects and where the ideas for the stories came from. This has to be some of the more in depth and extensive special features for a television series I've seen in a while and for those interested in what goes into the show's making it will be fascinating watching.
However, the real reason to watch or own this series is not the special features. It's because the thing is so damn good. Not only is it well acted and well scripted, its exciting, intelligent and funny. There some fairly graphic violence occasionally so you might want to screen it before letting young children watch, but it would also be well worth their while to see this because it makes history so fascinating. In this world so obsessed with the future paying so little attention to the past, it's a joy to watch something which recognizes the significance of history. That's a lesson we could all stand to be reminded of.
