What are your opinons on abstract art?

What do you guys think of abstract art. I think some pieces like the starry night I can appreciate, but really contemporary pieces, I just dont get. Some pieces are just like 3 colors and I feel I can create it too? Is it just me that cannot appreciate this art or can someone explain how to decipher these pieces. I think there might just be something I dont understand because many of them sell for millions. The one I attached sold for 98 million!
