As a "pretend" (as I can't call myself professional in any way) artist, I feel pretty ashamed of this "modern" art aka crap.
What I ask is for a piece of art is for the very least to look like someone broke a sweat over it.If it looks like something a 3 year old could draw, it's not art, it's doodling.
Secondly, I'd like for it to do something interesting with it. That's why I love symbolism- it's the perfect combination of what I love-good art and good ideas.
Like this:

(translation: "this is not a pipe". why? because it's a drawing of a pipe, it's not a real one

or even

(it's supposed to represent an infinite tower)
Thirdly, just for me, I like photo-realism:I like for an artist to be able to reproduce reality as it is (like the Renaissance artists) . Nothing says effort like doing something as perfectly as possible
However, people like Picasso (who is actually a good artist, but decided to use a specific "style" reminiscent of an ADD school-kid) got the fad of shitty art "in" , and while I don't mind Picasso so much, his success sparked a wave of shitty doodlers who wanted to cash in and used "artistic licence" as an excuse to promote their bad work to real galleries, and the elite ate it up.
This led to more and more trends that went from bad to worse, till now everything can be called "art" with a straight face (hence the urinal thing)
No, I don't approve of these things, since these people aren't real artists.
If you are expressing your "feelings" in a bloody colored mess, then keep it to yourself, trying to scam people out of money for it only makes you a jackass.
To quote Yahtzee "if i make a joke and nobody laughs, i can spend the next half hour explaining the joke and getting a few "oohs" and nods but i still failed since nobody laughed!"
