I definitely see the points you're making about the way the plots were for the Borg. I was able to take it up to and including First Contact...but I think it went way too far with VOY and ENT.
Now, what about the costume aspect? Obviously one costume was done on a lower budget for TV, not for the movies, but still, if you look at what they were trying to accomplish--which one did you find freakier and why?
