Episode 78: The Impossible Astronaut/Day of the Moon

Siskoid and Ashford discuss Steven Moffat's The Impossible Astronaut/Day of the Moon, the two part opener for series 6.  There are so many beautifully directed episodes in this series, and this two part opener is no exception.  Moffat takes the timey wimey and ups it up to...11.  Sorry.  The T.A.R.D.I.S. crew's adventure is in America.  The United States of America to be specific.  And now, for the first time as far as a television broadcast, the Silence is introduced. Ashford really enjoys this villain.  What are your thoughts?  Are they all style and no substance?  Or are they actually worthy foes for the Doctor and company?  Did we mention this two part story includes Richard Millhous Nixon?
