Seeing the thread title made my heart leap a bit, but for a very different reason:
The romantic subplot that COTEoF hinges on for emotional resonance with the viewer is rushed, frequently cliched, corny, and I never believed Kirk was in love with Edith Keeler. 50 minutes is not enough time for such a substantial payoff.
There, I said it. I feel better. Don't get me wrong, it's likely in my top 20, but it falls heartbreakingly short of greatness.
I originally felt the relationship was simply a story telling device and that a love that deep couldn't have been formed in 50 minutes, myself. However, I just read David Georges Crucible: Spock and realized that they were there in the 1930 for approx 45 days. I still don't believe a lasting love can be formed in 50 mins but I am much more amenable to 45 days. Particularly as George portrays Keeler as an extraordinary woman who was ahead of her time and very much in sync with Kirk's personal philosophy and belief system. Not to mention very attractive. I highly recommend the book to anyone who is not satisfied with the few minutes we get of the story on screen - good as it was - and now even more of a personal favorite.
