Breathtaking

"Through the Wormhole" is, quite frankly, all over the map. It's alternately superficial scientifically, then almost inaccessible. Yes, Morgan Freeman has a fantastic narration voice, but it's really not that informative. Like most Discovery Channel-esque series ostensibly explaining "hard" science, it's really just a glitzy presentation with high-profile talking heads either talking in obfuscating jargon or simplifying things down to a level that's nearly pandering.
It's better suited for a junior high / high school science class, to try and get some more kids interested in the subject matter than it is to actually inform viewers.

"Wonders of the Universe" and "of the Solar System" do a far better job of actually explaining the material, in part because the show isn't written on such broad, semi-sensationalist topics. It doesn't try to be "sexy," it just tries to be informative and passionate. As far as science goes, it's a superior show.
I will admit that Brian Cox isn't the greatest of presenters, but he really grows on you if you don't go into it looking for glitz and glam. His passion for the subject material really bleeds through, and he has an amazing knack for drawing concise but informative comparisons and metaphors. Of course, because it's a man with a non-American accent spray-painting diagrams on a soon-to-be-demolished wall instead of Morgan Freeman doing voice-over of a cheesy animation sequence, nobody listens.

It's a darn shame. I find the subjects of astronomy and astrophysics absolutely fascinating, but my ability at math is prohibitively poor to have studied them in college, so I'm left to television specials/series, beginner books, and continuing education seminars to learn more about it.
Shows like "The Universe" and "Through the Wormhole" are great for the exposure and for drawing more people into topics that have been labeled for decades as "boring" and "irrelevant," but they don't really teach much. They're just a doorway. The two "Wonders of the..." mini-series are a taste of what you can find if you actually go through that doorway.

But, they're never going to be as popular. After all, Brian Cox "talks funny" or "looks like a little troll." Everyone's entitled to their opinion of course, but quite frankly I'm embarrassed by the number of people I've talked to, online and "in reality," who say they turn off these series after about five minutes because Brian Cox is "weird" (by which most of them meant, in an attempt at sounding less xenophobic to me, "isn't American.").

NB - the negativity isn't aimed specifically at anyone in this thread. It's a general comment, and I simply have an ingrained habit of hitting "reply" to the last post in a thread.
