Advertisements I liked it as well. I thought the course difficultly was just right. They had plenty of finishers, but a few qualifiers that did not finish the course. The rolling ring obstacle was neat, but enough ninjas were able to complete it, even if they did not catch the ring, that it did not seem too difficult. I assume that we are going to see the same obstacles for all four qualifying rounds? That way it was easier to film and edit together in to four episodes.
