This program must have been made for the Joe Bloe uneducated TV viewer. Most of the time, the information being presented is not new or interesting, and it feels as if the writers & producers of the show had to fill up a large time slot with very little source material. So what you get is a bunch of information repetitively going on and on about how "dangerous" gamma ray bursts are, or how imminent asteroid collisions are, blah blah blah. Yes, we all know about these things, but the way the program makes you sit through an hour meagerly trying to make you sit on the edge of your seat for a statistic of like 1 in a billion billion (as seen with the gamma ray bursts) that the Earth will be destroyed by some calamity. Yes, we know already! They could have been done with it in 5 minutes, but no, it's stretched to an hour long program! The sensationalism of this program is just too over-the-top, from the drawn-out "fear factor" bits, to the announcer's XTREME TRUCKS style voice. They obviously should have saved him for the Monster Truck series...
Another thing that bothered me were all the "analogies" that took away from the true dynamics of how certain things in the universe work. For example, dropping a Yogurt container to show how a death star works... or a sprinkler for showing how a spiral star is. While these are "cute" they are indeed more annoying than useful, and assumes a real lack of intelligence of the viewer. Just tell us the science behind it without treating us like 5 year olds.
It really is a shame. This program could have been so much more informative and hosted by a much better narrator (writers are to blame too, of course). There are indeed moments where I laughed out loud because of how dumb the narrator's comments were.
On the bright side, however, the computer effects were done well enough. It is an interesting subject, so that's why I gave it a 5. But all in all, terribly done for such a great topic.
