Its sheer quality matey, its along the lines of the movie. Its a pity they never made a second series really, and they don't show it often enough, especially on mainstream TV.
Its been on Men & Motors recently, but I havent been able to catch it and only found out it was on the other day, its half way through the series and really you need to watch the whole series one after the other to get the jist of what going on as its a ongoing backing plot, with individual storylines for each episode. Im gutted really, cos if I had known it was going to be on M&M I would have series linked it on the Sky+ and then archived it onto VHS lol!
The pilot episode was especially good from what I can remember, although it was very long, like nearly 2 hours lol!
