Maybe you'd have to be studying art or interested in discussing/arguing art to find this stuff pleasing.
I dunno. No one seems to worry too much if they don't like or understand a piece of music or a book or something. I think if you liked every piece of art you see, then you can't have any critical abilities at all. There are so many different styles out there, it wouldn't be reasonable for every piece to suit everyone - we are all different, we all have had different education and experiences, and we all have different tastes. There will be things you don't like, and that's fine.
Of course, knowledge of the history behind the artists and times a work was created in can give you a greater understanding of it. There are works you can appreciate for the skill in creating it, or the idea, but sometimes, even knowing that, it's not going to click with you. This one probably has worked in that we're discussing it with a thread on MN.
I think visual arts are often different from music or literature. We tend not to see novels until we get the finished product - edited and refined, draft sections rewritten and thrown out. Similarly with music, you mostly don't hear rehearsals or trying stuff out, unless you're actually part of it. Generally, we hear the final recording, or a well-rehearsed live performance (unless you watch BBC4 late on Fridays...).
But with the visual arts, these days, we seem to see lots of sketch books and doodles where people were just practising, trying out ideas and stuff. It was never intended for display. It is often interesting to see the process, but I think there can be pros and cons to it, when you get every scrawl an artist has ever made, just because it's Picasso or someone. Although he was so important to 20th century art, maybe it's understandable that people want to try and work out every thought he had.
In any case, this work isn'the all the preparatory drawings and plans. It's the end product. And in the end, even if you have read all the curtain notes and so on, and still think it's a load of bollocks, that's okay. It's made you think about it and talk about it, so it has had some value. You're going to remember it - I'll bet there were other works you don't remember having been in the gallery at all. So was it completely worthless, even if you don't think the artist achieved what the notes say, even if you don't like it or think it has any merit?
It does look like a cattle crush, though.
