There was a series on NBC some years back that I really liked. Does anyone else remember Dark Skies...? It starred Eric Close and J.T. Walsh, and a pre-Star Trek Jeri Ryan. I thought it did a really interesting merging of alien invasion and JFK conspiracy theories. I believe it was only one season...though that one season spanned pretty much all of the 1960's... I'd probably pick this up if it was released on DVD.
