Review: When the opening began, I figured this would be a straight-up Game of Thrones reference of an episode. It ended up as more of a basic medieval-themed episode albeit with references to GoT and other similar worlds. A lot of it was terrible, though. The main plot focused primarily on Marge, Lisa, and Jacqueline whatever-her-last-name-in-this-world-is, and it is a terribly dry plot at that, medieval themed or not. Most of the jokes either fell flat or were just embarrassing (one "Krusty has genital Smurfs" was stupid enough, I didn't need several more of it). You can categorize this under the already-stuffed "episode about thing writers like but have no idea how to properly parody".
Final Score: 3.5
