Our reading
An editorial interpretation.
A backhanded compliment stacks two contradictory judgments together, first mocking someone's dramatics before immediately praising them for the same trait. The line captures a knowing, theatrical wit that finds grandeur in excess, admiring the very self-indulgence it just finished criticizing a moment earlier.
