I'm by no means trying to contradict your point, I just wanted to add that I haven't seen any of the old movie serials you mentioned and I still enjoyed this episode immensely. I almost didn't recognize Janeway! =O She looked so... Adams-family-esque!
I also thought I might add, I have this funny hunch that Voyager is the Star Trek series that is "for girls." >_> And when I say that, I mean it in only the best way.
As a Star Trek series, Voyager has almost all of my favorite characters in it, and, oddly enough, almost all of them happen to be female.
