Picasso was pretty good at drawing random lines that mean nothinge except to those whose minds are deranged like his was. Looking deeper into his "art" however one does find a gteater depth of insanity and confusion.
Picasso was a bum and his work was puerile and worthy of display only in a 2nd grade poster paint display.
Picasso was a child prodigy. Some of his earlier paintings, done when he was in 13-14 (and which, btw, are completely realistic) are wonderful. They are beautifully executed and are remarkably affecting. Of course, you never see these paintings, and in fact, all you ever see is Picasso after he became an industry.
Actually, he made himself an industry, and in many ways, you can't blame him. He took the gullible and celebrity-worshipping reviewers and turned their pockets inside out.
Picasso was, in many ways, the ultimate artist's revenge. Forget artistic integrity. He found a product that sold, kept on producing it, and lived very nicely off it, thank you. (I think he once boasted that he could even sell his sh*t, although I don't think he tried it.)
