Fall 2011 shows that are worse than “The Sacred Blacksmith”
Shakugan no Shana III > Maji de Watashi no Koi ni Shinasai > Kyoukai Senjou no Horizon > Mashiroiro Symphony
Shana may actually have the worst script of the four, but at least it’s classically bad. The horrifying creature in Mashiroiro ensured it the lowest spot.
Speaking of horrifying creatures, I can’t seem to remember what the point of that scene in Fate/zero was.
