What an amazing episode. SGA's fourth season has mostly been a disappointment, but "Miller's Crossing" makes up for that.
David and Kate Hewlett's acting was superb and Joe Flanigan was perfect in his portrayal in trying to get friend, Rodney McKay back from kidnappers. The John and Rodney scenes were some of the best acting between Joe and David I've seen in the four years of the show.
Martin Gero (writer of this episode), deserves high praise for nailing dialog, characterizations and the mood of the episode. I want Mr. Gero to write all SGA eps from now on!
I'd give "Miller's Crossing" a 10 out of 10.
