"I'm a busy man! I need to know what art is worth spending my time on! And G-D-it, Wikipedia, it's your job to help sort it out for me!"
It's ironic (and worth noting) that I simultaneously can think this and also understand that any piece of art that I am personally likely to classify as "great" will capture a concept in a way that will not be able to be explained adequately and will only be fully understood upon viewing and comprehending the piece itself.
In other words, the things that I find "inadequately" explained on Wikipedia (I say "things" meaning art) are likely to be the things that I will most enjoy. So I apologize, Wikipedia, for thinking that you were slacking off. Keep up the good work.
