Anyone that is interested in this material won't be surprised by the content, and in fact will be bored out of their minds by how often they repeat themselves within each episode, and within the series itself. For instance, four separate shows deal with black holes, under thinly disguised 'different' topics.
I found most of the analogies that were used not only wildly inaccurate, but downright misleading and horribly contrived. This does not even touch on the voice-over sensationalizing and distorting what little facts are actually presented.
This would be a good show for third to fifth graders, but no higher than that.
