Darmok and Jalad at Tanagra. This seems to be everyone's favorite episode of The Next Generation. I see a major plot hole in this episode. For those who are not familiar, Captain Picard encounters a race of aliens who only speak in metaphors. Darmok and Jalad at represents two enemies who crash landed on a planet and had to work together to defeat a common enemy. Here's the problem that the writers missed.. you can't have a language of only metaphors because in order for the language to pass down from generation to generation then you must be able to explain what the metaphors mean. How do you explain what the metaphors mean ... ..if you can only speak in metaphors?...my reply....Gene Roddenberry with illogical plot
