I managed to completly miss this series on tv and i purchased it hoping it would be as good as i've heard. It was, and it is great to be able to watch all the episodes in all six series back to back. The series are themselves packaged nicely within the outer cardboard sleeve. They all come in a slighlty larger sized series box, which means it is easy to get all the seperate discs out easily and it looks very nice.
The series follows two brothers, one a FBI agent, the other a brillant mathematican, and showcases maths against FBI cases. The use of graphics to demonstrate the maths problems adds a nice element to the series, and helps you to understand the cases a little better. The programme has been well written and produced, and so even watching back to back, you don't get a sense of repetition nor boredom at watching so many episodes. Definatly a keeper for your DVD collection.
