The interplay between content and presentation is a symbiotic relationship where either side can drag down the whole. I loved the content of the Frisby egghead course, but have to admit that I had trouble finishing it because the presentation became tiresome for me. I also felt like I couldn't listen to it within earshot (or view) of anyone for fear of looking like a child watching cartoons.
There's no point in attacking the course based on this aspect of its presentation. If it were super polished but made a bunch of mistakes, that's when you need to shout loudly to anyone you care about "don't watch that course! It's full of mistakes!"
