This Guardian piece offers vignettes from critics of various types who have had to deal with a bad reaction to their insights. I particularly liked this story from Phil Daoust, a former comedy critic:

In 1998, a few months after I gave Steve Coogan's live show, The Man Who Thinks He's It, a lukewarm review, a friend ran up to me waving the comedian's brand-new video, in which a recording of the show was topped and tailed with fake behind-the-scenes footage.

"You've got to see this!" my friend said.

There Coogan was in his dressing room, in gown and hairnet, spitting on a copy of the Guardian, effing and blinding about me and my review. "'Doesn't take risks!' 'Doesn't take risks!' he fumed. "What's ... What's taking a risk? Is skulking in the shadows of a theatre making snide remarks about someone who makes 3,000 people laugh every fucking night, is that taking a risk? I'll tell you what taking a risk would be - for Philippe Daoust to meet me down a dark alley. I'd shove his three stars up his arse."

He'd obviously done his research. My byline has always been Phil Daoust, and only a few people know my full first name. "I've made this," Coogan went on, brandishing an evil-looking contraption. "It's a toilet chain stuck into a ball of Plasticine with fish hooks on it. I can use that as a weapon against him if I meet him. I'd swing it into his face and the fish hooks would stick, would stick in his cheek - like that! It doesn't hurt going in. It's when it comes out - it pulls a big chunk of flesh out of your cheek."

I was delighted, of course, as most critics are whenever we get a reaction. I still have the video, though the tape's wearing a little thin now.
