Query: Disappointing

The author, Chevalier, had a good idea of weaving a story around a famous painting, but this book is a big let-down; it was downright boring. Considering that Chevalier has a degree in creative writing, she does a poor job writing this book creatively. The characters are dull and lifeless. What's more, you just don't care about any of the people in this book. The ending is so predictable - I didn't even have to read it. I don't know how anyone can rate this book highly or recommend it, and I can't believe it made it to the New York Times bestseller list.
