If there was any kind of theme to the season, it was moving forward, most obviously shown when
Voyager itself was thrown forward 10,000 light-years by Kes on her way out the door at the top of the season, and then the ship gaining another 300 light-years thanks to a juryrigged quantum slipstream drive at the end of the season. Just in general,
Voyager emphasized making progress, not pausing long in any one place, and while there were recurring antagonists like the Hirogen, most of the nations encountered by the ship were left behind in short order. And even the Hirogen encounters were all bunched up.
