The show is relatively short - really, a sort of teaser for material covered in greater detail elsewhere - but it's perfect for giving a taste of individual guests and subjects. But the interest varies. It also ranges from a little under two minutes to just under ten, giving the feeling of inconsistency. I particularly liked a speaker's admission that the concept of "dark matter" was only a "spacer" for science's flagging knowledge on the subject.
The show and its subject matter deserve a more dedicated treatment; as such, it's intermittently interesting.
