I'm of the opinion that you shouldn't need a degree just to get some enjoyment out of it.
While I have a degree, it's in physics and my last art class was back before GCSE. I still enjoy wandering around the Tate Modern every few months.
Some bits are pretty crap, but even some of the simplistic works are pretty impressive in person.
I remember rather enjoying this piece, despite its simplicity. It looks even simpler on that page, but in real life it's size and the slight optical illusion effect was impressive. The same room had
this work which takes a not uncommon optical illusion and blows it up to three 2m x 2m panels. You literally can't see the effects in those pictures but it was rather unsettling in the room.
The story behind the urinal (known as 'Fountain', although the original is lost and they currently have a ceramic replica on display) is
worth reading. The work itself isn't that impressive. The context and original subversive nature gives it a different meaning. I don't see this as any different from going to a museum and looking at any other cultural artefacts. The object itself is only a tiny part of the story and often the least visually impressive items have the most significance.
Actually that reminds me of one of the Tate's temporary displays; the photomontages of
John Heartfield taken from the covers of AIZ magazine in the leadup to the second world war. Contemporary anti-Nazi art that basically charted the rise of the Third Reich. The most powerful image was of Hitler's face, mouth open to consume Europe. Except that the entire run of that issue of the magazine had been censored. Even the copy on display. It had been coated with a layer of black paint, with the original image just visible through it. Made it more powerful than the rest by far.
