This is a great episode, one that I still rewatch. The acting is excellent. My favorite scenes are the confrontations between Jarok and Picard and between Tomalak and Picard.
I thought the set up of the secret Klingon back-up was very well done as well. We get only a few off-hand mentions of communications between the Klingons and the Enterprise until Picard reveals them to the Romulans.
I thought it was nicely done as well. It was one of those WOW moments for me when the reveal was made.
