Anwar said:"Living Witness" is written off as a failure because of the EMH backup plot point (the audience gets a well-written story with great acting from Picardo and NONE of it matters because of the Backup plot. They let one minor plot contrivance ruin the whole episode for them). Shades of Grey is excused as "Well, there was a strike so they needed a clip show." with little to no complaint.
I can't say I've ever encountered this view-point anywhere before.
"Shades of Grey" is one of the most reviled Star Trek episodes ever made, it certainly never gets excused as summarily as you describe. "Living Witness" is an episode that gets a lot of praise. It's one of Voyager's most acclaimed episodes.
Despite going through this thread, and my own research, I cannot find the evidence for such claims.
