First series I watched was TNG and then Voyager. Also looked a lot at Enterprise, DS9 and TOS. Discovery I started watching but I’m not as interested in that one, to much war there.
As for OT – “just graduated”, then TOS era is of course the winner and as for uniform I don’t mind red since while they where most often killed they where also the most of them. I mean if 10 red,1 blue and 1 gold beam down and two red and one blue is killed does that mean red is deadlier?
Yes, lots of interesting characters like Yeoman Janice Rand/Grace Lee Whitney (who is the one who convinced Gene Roddenberry to have minidress as uniform to show off her legs), nurse Chapel, 7of 9 and so on.
Then we have reoccurring guests that are far from bad but those skinny people is only something to dream of.
The one I at least have a remote chance to dress like without being a shape shifter would be Lwaxana Troi. I like what she wear (except her wedding) but her larger than life character is nothing I would be able to do.
