I always liked Jellico. Well, perhaps liked is the wrong word, but I don't think he deserved the disdain he got from Riker.
Jellico might have done things differently to how Riker wanted, but he was bought in specifically because of his experience in handling the Cardassians, which served him well. Heartless as it may sound, his decision not to acknowledge the covert mission into Cardassian territory was the correct one. Jellico not only averted war and a huge embarassment for the Federation, but he still managed to secure Picards release.
Has to be one of my fave episodes though. Patrick Stewart and David Warners scenes were compelling. And just when you think the episode has gone the usual route of having the hero hold out under questioning, Picard admits to Troi that he was infact on the verge of breaking.
"You ain't gonna get off down the trail a mile or two, and go missing your wife or something, like our last cook done, are you?"
"My wife is in hell, where I sent her. She could make good biscuits, but her behavior was terrible."
