No, it's probably just that you see art as something to casually consume which you expect to provide some form of enjoyment to you. And there's nothing wrong with that. But if you invest some time into studying art, its history and what has been done in the past centuries as an ever increasing share of mankind's time has been freed from satisfying basic needs, you soon realize that "it's all been done before". Doing anything that hasn't alreadly been done, and done better, by some prodigy 200 years ago, is almost impossible. At least if you work in a traditional medium like paint or theater. So if you're an artist who wants to do something truly original, you can either switch to a technologically new medium (and realize that quite often you're still riffing off something existing), or you can start to question the "needs to be realistic, pretty or otherwise enjoyable" requirements. So what modern and postmodern art does is, very roughly, to drop those requirements and instead ask questions like "what other crazy things can we do with this medium?" or "What other emotions can we provoke in the audience, how and why?" As the audience, it's best approached like a puzzle.
