I would say that Atkinson wasn't generally quirky or humorous. He was reportorial, that's the best word that comes to mind. Even his Sunday pieces are sort of unshowy, and he rarely if ever indulged in the kind of rhetoric that is in this fake review.
And the Kerr review is missing both his quirkiness and his analytical skill. And the prose is flat-footed, which was rarely if ever true of Kerr's reviews.
