What a shame this had to be the final season. Perhaps darker and more confusing than the previous seasons (we didn't guess the bad guy in quite so many episodes this time), it brought the story to a fitting end, although my children and I wanted more.
Great to find a programme that made Maths cool and interesting, even my daughter, a real Mathsphobic, was intrigued.
Although we initially found this series more by accident than design, we have been hooked throughout, very difficult with over 100 epeisodes, but not once were we bored and to hold the attention of teenagerrs is saying something! I am not really a "crime" fan but this was thought-provoking, humerous and generally more interesting than previous series, more personal. You really felt you knew these people and the dilemmas they faced in both their professional and personal lives - definitely think the family link between Alan, Don and Charlie enhanced this and made it special.
Would love to see another season, but perhaps they bowed out at the right time, on top. Definitely one to watch and keep!!!!
