Whew! RL has been hectic, but I finally got to watch the episode this morning. I'll try not to repeat what others have said.
Once again, I'm impressed by what an ensemble cast can do. There were even added minor characters this time, with Cutler and Novakavich. Everybody got something to say, and Travis and his ghost stories! Very funny! I liked that the ghost stories were current to their era, that is, they involved space.
It was interesting that it was the minor characters (except for Trip) being impressed and awed, looking up at the night sky when they're camping. Then the scene shifts to the bridge, and for Archer and the crew there, it's business as usual.
I felt for Cutler at the beginning. She's trying to make small talk with T'Pol, who cuts her off. I think Cutler in this instance embodied some of the spirit of humans as they started moving out among the stars. She's trying hard to be friends.
Archer is reckless in sending down a party without checking out the planet first, but some of that, I think, comes from the feeling of being held back so long in their effort to explore space. This episode shows that there are consequences in not being properly prepared or cautious, and hopefully, it becomes a lesson learned.
The calmer and more logical T'Pol was, the more it seemed to drive the others, particularly Trip, to disagree or become angry. That may have been the effects of the hallucinogens already working.
I did wonder, though, why T'Pol didn't realize that something was wrong with the humans in the landing party sooner. She had been around humans enough to know that this was extreme behavior even for humans.
In reference to some of the other comments about the spores/flowers, I was wondering if the reason Trip seemed to hang on so long (unlike Cutler and Travis who were falling asleep or were unconscious) is that he had more adrenaline to work with, having gotten angry at T'Pol. It did seem that the humans were affected according to their biases. Trip distrusted T'Pol, and there was more than the usual hint of T'Pol's disdain for the irrational behavior of humans. Travis seemed the least affected; that might be because he grew up in space and had more contact with unusual things. Novakavich, cussing out his captain, leads me to believe he might have a problem with authority.
Best line -- "And I have a phase pistol pointed at my head." Jolene delivered that line with such matter-of-factness that it made me laugh.
I never noticed this the other times I watched this episode, but T'Pol uses a Vulcan nerve pinch to subdue Travis to give him the innoculation. Then he complains that his neck is stiff or sore. I don't remember, but did T'Pol ever use the nerve pinch again in the series?
I loved the little lightning bug-type bugs flitting around during the camp scene.
Old enough to know better, but that's never stopped me before.
