Which I saw Harlan Ellison do once: in his review collection Harlan Ellison's Watching (1989), he put a footnote to his 1966 review of Francis Ford Coppola's You're a Big Boy Now! that was longer than the review. (He wanted to explain why he was finally publishing the review 20-plus years after he'd first written it, detailing in general why he's often painfully honest, and even took himself to task in the footnote for how bone-headed his review was.) Another reason I'm glad Harlan exists.

I don't have enough brainpower this close to going to bed to say more than that.
