That of course was always the criticism, but millions thought otherwise.
There was a time when I really disliked Dire Straits for being too ubiquitous - around Brothers in Arms, every track of that album was played to death, but these days I've made my peace with them. I never saw them, but I've seen Knopfler. He's no showman, but his guitar playing and the musical storytelling are nice to listen to. It's a bit like going to a Pink Floyd gig, the 'action' on stage won't excite you, to put it mildly. There is a light show to look at though.
