It was not just two teams playing cricket in the Ashes series, it was two philosophies facing off, two systems asking the (cricketing) world to choose between them.
In the end, 2-2 was a fair result; after all, the effects of a revolution may not last as long as gradual transformations do. And Bazball needs tweaking, so a 1-3 loss would have been a setback for Ben Stokes, Brendon McCullum and their mission to win entertainingly.
