To be honest, I saw it as a waste of time. When offering a critical account that deeply challenges what people perceive to be reality you have to then explain how the systems within it work in your new version. That's what all the great scholars have done, some were even imprisoned for it. I would even say that explanation of those systems is what led to them forming a world view rather than the other way around. Can you explain how gravity works on your flat earth? What central mass are people drawn to? If any?
Apologies for the slander, but this is old ground
