This could apply to any form of professional critic. There is a very small proportion who serve a useful purpose, a "reviewer" if you like. Most of the others seem to be unnecessarily cruel and I'm not at all sure why

Haiku for a newspaper critic



You quiffy, farty, shiny face,
you think you're the man,
but you can't hack the pace.

Twatty, tossy, poofy arse,
smirking moron,
your life's a farce.

Judging people,
sneering comment,
no talent feeble,
you make me vomit.

I see your fame,
I hear your words,
you're playing the game,
throwing turds.
