Not sure if I have enough intrinsic motivation to be a professional critic of anything. Sounds like a lot of work to me. Although if I were paid some ridiculous sum of money just for stating my opinon about stuff I suppose I’d already have more money than God.
Professional critics should be qualified experts in their fields if they want to be taken seriously. I’ve never run a catering business or written a novel or directed a movie, so whatever I say about food and books and film is bound to be a purely subjective value judgement, having very little to do with rightness or wrongness or usefulness or meeting some lofty standard of excellence.
I like things, or I don’t like them, or I’m completely unmoved by them. An opinion on art is probably the most worthless opinion there is. Although everybody has one. So give me Art Critic as a profession, thanks very much. And pay me incredible amounts of cash to stand around sipping wine in art galleries all day. All I need is a notepad and a thesaurus and I’m good to go.
