Modernism - yay or nay

Modernism is so unique in the way that the different pieces can be so extremely different from each other. Some of them I think are really cool, a lot that I don't see the beauty of until after learning about them, and others I'm like "wow you should've stuck with Impressionism." There's cubism, expressionism, and so many different styles inside of modernism. Van Gogh for instance is so different from Picasso. Many pieces seem like they would take almost no skill when in reality they've gone through a lot of thought and have more heart in them. Many seem almost cartoonish with their black outlines and shallow depth, while others hold intricate geometric shapes or purposeful unbalanced perspective. Modernism is so wide and strange with such a large variety of painting styles within it.
