The thing which surprised me is that it somehow felt smaller
than First Contact. And more cloistered too, in a funny sort of way. FC actually felt bigger and bolder and more "in the open", which is somewhat ironic because INS featured literally more external scenes away from the Enterprise than FC and costed way more money to shoot. I think FC was just better at suggesting its world, hinting
in a way which makes it seem so broad while the size is actually scaled right back. On the other hand, INS kind of puts it all up there on the screen and then doesn't do anything interesting with any of it.
I always thought Insurrection
felt "small" because it was about a few hundred people on an insignificant planet in the middle of a region no one cared about. In First Contact
, the fate of the entire Federation was at stake--if they failed, everyone would be Borg. The stakes were higher and the scale was larger.
