This started out to be a promising episode of Dr. Who. However, quickly Went downhill from the beginning. I really would've loved to find out what had happened to the astronauts who could come before and why there we're spiders on the moon. However, what I got was a morality play about humans making choices. That would have not been so bad if the science was so outlandish. There is no possible way that the people of Earth and more than twenty astronauts would not have known that something was growing in the moon. As soon as an asteroid hit the moon then the "egg" would have cracked open and the mayfly would have escaped. Then there are the inconsistencies within the series itself. The Doctor had previously visited the moon in his tenth incarnation to fight the Judoon, and never detected any inconsistances and the second doctor fought the Cybermen on the moon with no indication of a life form inside the moon. Finally, the Dr. Who adventure, Waters of Mars, occurred 10 years after the supposed date of the events of last nights episode which supposedly occurred in 2049. Dr. stated that people there had abandoned the space program. My question is if humanity had abandoned space travel then how could they have put together a Mars Colonization program in under 10 years.Doctor Who used to be destination television for me but at this point I am just hoping that 12s regeneration is a short one and that if there is a season nine that it is a drastic improvement over the current series.
