The problem is that liking it should be playing no part in judging it's merit as a piece of art. Liking it IS subjective, and that is where the confusion happens. There's so much artwork I don't LIKE... meaning I'd never, ever hang it on my wall, but it's still brilliant work. By "liking" and not "liking" you're just deciding that and nothing more. If we judged art merely by that standard, there would be no standard, and no means of judging it. There are some images I like looking at, but have to confess there's no merit to them as artwork - they're just pretty - chewing gum for the eyes, and conversely I've stood looking at some stuff in galleries and been horrified, but the fact that it held my attention for so long, and made me feel that way when considering what it was showing me, and why, that I had to just concede that it was utterly brilliant. I still didn't like it, nor would I want to look at it every day, but so what?
The untrained viewer just likes what they like, and dismisses what they don't offhand without any deeper thought, reflection or analysis. It's all surface judgements. That's a little like judging a car based on what it looks like without considering what it actually does, or how well it does it. You don't read a copy of Auto Car (or whatever) and expect a review of a car to say "We like this... it's pretty" and that;s it. You;d think it was a pretty crap review of that car, yet many, many people do exactly this with art. "I like that"... bang... and therefore it's art. That's pretty ludicrous when you think about it, yet that's exactly what most people do.
"I like what I like".. well... errr. yeah.. of course, but so what? Can you say why you like it, and if you can, do those reasons qualify it as a great piece of art, or merely explain why you like it? I like HP sauce... it doesn't mean it's art. Now.. many will be thinking, "But I don't care about all of that arty crap... I just like what I like".... and that's fine - Utterly fine. You really have no part to play in a discussion about what does, and does not constitute good art though, as telling us you like it is meaningless in such a discussion. If you can tell us why, and justify it well, then mabye the outcome will be a consensus that it works as art, and has merit beyond being pretty. However... that conversation needs to be had, just as the car review needs to analyse the car, it;'s performance and everything else that isn't a surface judgement based on it's looks alone. "I like what I like" is an utterly meaningless statement.
