sekundant, lemme take a wild guess...Andorian Incident?
You got it
@HopefulRomantic .
Maybe I have to correct myself. Andorian Incident (AI) is "one of the" my all time favorite. The episode has everything what a geek hearth desires, from action to B-Movie dialogs, everything. And all these elements rounded with a good story.
It is a game changer kind of story and tells us this Vulcans are not your mothers Vulcans, they are different, which is highly logical. Even old good Heraclitus said “No man ever steps in the same river twice, for it is not the same river and he is not the same man.” for 2500 years before. Why should be believe in one day we will become a society without money, without poverty, without racism, without greed, .....without all those horrible things, if we think all other societies never changed? Archer's dislike of Vulcans, his delusion about becoming emancipated them seem rather personal issue until AI. He was more radical at his attitudes even than his father. And we had T'Pol who doesn't seem to be a saboteur or hostile motivated. Independent of their personal relationship, we realized the problem is more complex and more dimensional than Archer's private war.
Additionally, there is another player on the board which is unknown until now. It was a genial twist to bound another great TOS alien race to ENT narrative. Interaction of three races war real fun: ignorance of space tourists Archer and Trip, ascetic Vulcan monks, brutal Andorians. We see something and at next we realize it is an illusion and the cards will shuffle again.
And we will be witness of some prophesy moments: not only T'Pol's loyalty to Archer but her loyalty to herself as individuum (Achtung, for a Vulcan!), begin of a great bromance, the very first step to through Federation. If you don't understand AI, you will never get the spirit of ENT, imho.
We get funny Tarantinoesk moments like smelling humans, subtil blanket fight, Archers investigation..
And contrast of amazing premiere of Jeffrey Combs as Shran and cringey performances of Vulcan monk/ spion and Androian randy officer. Breathtaking sight of P'Jem from outside and cheap decoration of inside.
Ahh, I can talk about AI endless hours, so rather stop now.
