Query: Sub-par effort

I was very disappointed by this effort, esp. from Magnum, a name I associated with quality photography. Some pictures were "new" -i.e., not the usual crop of pictures we've seen. But even allowing for the fact that many photos were taken in the aftermath of the fallen towers, almost all the pictures looked "muddy," grainy and/or dull. Few, if any, of the photos popped out at you with clarity. A real disappointment. Life's commemorative issues (paper and hardcover) did a much better job, though with more predictable photos.
