If fans agreed on one gripe about Episode 3 of Game of Thrones, it was the darkness. The Battle of Winterfell was awesome. Unfortunately, many of us had trouble seeing what was going on because of the way the episode was filmed. The screen was so dark it was hard to tell who was who and to see the faces of the White Walkers and wights. That’s one reason I wasn’t alone in missing one of my favorite musicians, a superstar, in the episode. This star isn’t the first to be featured in a cameo on the series.
