Great show! I watched Season 1 with my son (10 yrs old), and it was a fun night we both looked forward to all week to watch an episode together. I loved the combination of adventure, real history integration, positive relationships, and Monte Python-esque humor.
We were so disappointed to find out it was not renewed.
I'm not surprised it didn't have high viewing as I had never even heard of it until the entire season had ended and it was already decided to not continue another season. Low viewership was likely complete lack of promotion, rather than the quality of the show.
It was refreshing to actually watch something new and different and we are sad to see it go.
Maybe we will get lucky and a cult following will open the right person's eyes to revitalizing production!
