Reading many of the threads here has made me realize how much I've forgotten. So last night, I decided to start re-watching TOS. I honestly have no idea when the last time was I saw these! Bad fan! No collectibles! 
I'm going to be doing these in airing order because that's how Paramount+ has them and I'm lazy.
This is mostly for me to keep my own thoughts in order, but feel free to follow along and comment.
The Man Trap. Damn. It's so good! A few things I noticed:

The Man Trap. Damn. It's so good! A few things I noticed:
- I know this wasn't the first post-Cage ep filmed (looks like it was 6th), but the world already feels lived in.
- Kirk teases McCoy when they first beam down and apologizes after he snaps at him - very believably friends and comrades.
- Uhura is teasing and flirting with Spock, even putting her hand on his arm (he seems to find his collar a bit tight there!). Even when she gets mad at him, there's a familiarity.
- Janice and Sulu seem to be friends/friendly. She even handles the catcalling jerks like she's used to it.
- The first redshirt to die is wearing blue!
- Lesson: Never follow the hot blonde.

- It's not sickbay yet, it's the dispensary.
- The ruins on the planet look vaguely Aztec but the statue in front of the Crater's home looks a bit Assyrian.
- The actor playing Green did a great job lusting after that salt shaker.
- I had completely forgotten about the plant Janice likes. In fact, I'd forgotten that whole scene! I think the bit at the end, where she says she's afraid one of the plants will grab her someday, was cut when I saw it on TV as a kid.
- I have to wonder how much I never saw because of that practice. I confirmed with my husband that we have the videotape (seriously) of Balance of Terror because he once mentioned the wedding at the beginning and I had never seen it.
- All the actors were awesome, especially De. I was very impressed with him playing "Nancy"-pretending-to-be-McCoy. Nichelle and Grace had some great scenes too.
- I see that the writer, George Clayton Johnson, also wrote several episodes of The Twilight Zone. I think it shows.
