Yes, it's a silly premise. No, the show isn't terribly accurate. But Boy,Howdy; is it engaging for a restless group of 7th graders!
As part of our Roman History unit, we watched two episodes of this series: "Centurion vrs Rajput" and "Gladiator vrs Apache". Say what you will about the show (and frankly, you could find a lot of faults with it if you were cynical and jaded and had no childlike joy in your cold, stone-like heart), but it generated a lot of discussion in my students.
It also left them with a bunch of questions and comments for the producers of the show.
Now, does anyone know how to contact the producers?
