I've been curious as to what other people's opinions are on the best writers in the Trek canon (shows/movies only). Personally, I've always been surprised at how little credit Peter Allan Fields gets. On TNG, he only worked on three episodes. He managed to write a great Lwaxana episode (Half a Life) and a great Alexander/Lwaxana episode (Cost of Living). Then he capped off his TNG writing with work on the teleplay of The Inner Light, probably the single best episode of the series. His ten episodes of DS9 were incredible too. He worked on most of the great episodes for Seasons 1 and 2, including Progress, Duet, and Necessary Evil. His other early episodes (Dax, The Circle, Blood Oath, and Crossover) were all great as well. He left the writing staff, but still did three episodes - For The Uniform (his only mistep, insofar as it's well written but Sisko is out of character), The Dogs of War, and, of course, In The Pale Moonlight. While someone like Ronald D. Moore was certainly involved with a lot more good to great episodes (considering how much more he wrote for Trek) I don't think anyone else pound for pound was involved in so many great episodes and so few stinkers.
