"The Cage" and "Where No Man Has Gone Before" feels more suited for a movie environment than a television pilot. In fact, in a perfect world, if I could make a wish, I would have had a movie trilogy featuring Pike, and then go on to have the TOS television show for five seasons (set years later). Also, I would allow for Young Spock being more emotional, who would later become the more rationale, more logical version that we all know and love. And, I would definitely have a running joke go on where NO ONE knows if "Number One" had a "real" name or not. Is she an alien? Immortal? Or is she just a human with a wicked sense of humor? I know that in some literature (fandom or legit), Number One did have a name. In fact, one fan-centric text had her be the older sister of Nurse Chapel (named Arianna Chapel).
Hopefully, we'll get more pre-TOS stuff in the near feature, though I doubt it...
