I just watched "Too Short A Season," and I totally forgot how much I loved this episode. I know it focuses more on the guest star than any of the main characters, and the old-age make up on Clayton Rohner is iffy at best, but it's still a very well written and (for the most part) acted episode - Rohner's "old man" acting is a little strained. The story is a good one and, even though it is talky, it has energy and is well paced. I mean, it really does crackle with energy. It is a direction I had hoped the series was going in: exciting, mature and thought provoking adventure. Taking the best of what made Star Trek fun and updating it into "modern" sensibilities. The show was really hitting a good stride. It helps that Wesley is nowhere in sight and that the guest characters had strong motivations. Not surprising to see D.C. Fontana's name in the teleplay credits.
Even the music was really good. George Romanis, providing his only score for Star Trek, captures the mystery and nicely accents the action during the phaser fight.
Top notch episode, one of my favorites, but one I rarely get back to. I remember really enjoying this one when it originally aired and I'm pleased to see it has aged well. An underrated gem.
No doubt, I'm in a minority here.
I'm glad this thread exists, reminding me there are other episodes to revisit than "Best of Both Worlds" and "Yesterday's Enterprise."
