Fontana really did understand that "alien" wasn't about a few bumps on the head, or even different customs. It was about an entirely different outlook on life (and death and everything in between).
Mmmm. As much as I admire DC Fontana, I'm flummoxed as to what part of her TOS and TAS work leads you to set her up as such an exemplar. She attempted to keep the Vulcans on the straight and narrow during TOS, writing memos and suggesting ways to keep hybrid Spock unique among both Vulcans and humans.
ST has done "alien" very well over the decades. The Children of Tama, Species 8472, ENT's Andorians, Benzites, Bolians, Betazoids, the Dominion races... Compared to all of those, what did we learn about TOS/TAS Andorians, TOS Tellarites, TAS Edoans, TAS Caitians, TOS Catullans, TOS Tiburonians, etc, that went beyond some non-human body features and a very brief statement of Andorian and Tellarite mindsets?
Please give examples of DC Fontana's aliens' "entirely different outlook on life".
Why not a dark green Vulcan?
Time, money, and the actor's willingness to spend
many extra hours every day getting thick dark green makeup on every exposed body part. And more time spent for Wardrobe trying to get all the green stains out of Tuvok costumes
every night. And repeat for his understudy and any stuntmen. The blueness of Shran only had to happen a few times each season in ENT. A dark green
lead character - for
seven years - is a very expensive statement on "race".
