Their music is considerably more intelligent than people give them credit for. Well crafted, sometimes challenging, always big and hooky. Some big, big songs. Definitely under-rated.
They have alot of popularity, but critics usually hate them. So I'm going to say they are underrated by critics.
Amazing virtuoso, versitile band with an amazing range.
