I'm wondering about the 'Monster of the Week' reference.
I only watched the reruns in the 70s. I had no fears about the whole series being about monsters. But that's not the first episode I saw. I have seen the term used to refer to "The Man Trap" before but wonder why people would think that.
I thought the flirting was a bit of fun, in no way I thought Uhura was being serious. I was more annoyed by Kirk's flirting in other episodes.
