I consider myself pretty smart, even geeky, but I also consider myself a more-or-less average joe. So, even though I appreciated this subject-matter more than the average joe would, I didn't appreciate how it was presented. It was too "pedantic, rigorous, and lofty" for my taste. Though it did more-or-less satisfy my curiousity about the finer parts of the theory, and physics concepts themselves.
It was hard for me to casually listen to it, and conceptually grasp it without replaying at least certain parts of it. You would like it, though, if you like a "rigorous" treatment of (the basic concepts of) physics. Essentially, though, it was over 2 hours of "only" eventually leading the listener to the proposition that the universe is (most probably) spherical and infinite yet unbounded.
And, of course, that motions and spacetime are relative, that gravity curves spacetime, and the "propogation of light in vacuua is rectilinear and uniform in the absence of gravity".
