Because of course they are. We're only a few years away from losing nonfiction television shows entirely. The History Channel took its first tentative steps into this area with Vikings, and this new show, Knightfall, will be its second scripted show.
The show comes from Jeremy Renner and Don Handfield's production company The Combine and Midnight Radio and A+E Studios. Knightfall will follow "persecution, downfall and burning at the stake of the Knights of Templar on Friday the 13th, 1307." In theory, this will provide a fictionalized look at why we still see Friday the 13th as an unlucky day. Triskaidekaphobics should probably give this one a wide berth.
On the one hand, Vikings is plenty entertaining and at least this idea is history-related, unlike a lot of History's recent programming. On the other hand, I have very fond memories of watching documentary after documentary on the channel when I was home sick as a child.
