McCullum has seized the England tour, made a success of it the middle order and if there is a criticism that he has not gone on to turn one of his seven half centuries across the three forms into three figures, consider they're still pretty rare in T20s, don't crop up for No5 or No6 batsmen that often in ODIs; and a half century is a lot better than nothing.
The old aggression has bristled in McCullum the batsman. Yesterday, he ensured that the momentum moved up when he arrived at the crease after an hour.
England were taken apart, double century-maker Fulton cheerfully filling his boots, too.
The cut of McCullum's jib may never be the ideal fit for every New Zealand cricket fan, but it can't be denied that with his front-foot attitude at the crease, allied to being unafraid to shuffle his field about, he's made this, in personal terms, a special series.
