All I have to say is... Great episode, though there were parts that let me down a bit.
Yes, there were things that I really didn't like in it, and I question the continuity of some of the stuff that was contained in the episode, but overall this was a remarkable episode of the series, saw some closure of certain elements of the current story arc, opened up a couple of new ones, and left us on a cliffhanger until November 23rd and the 50th anniversary episode of the series.
'Nuff said.
