I generally think that Voyager is the weakest of the Star Trek spinoffs, yes even more than Enterprise. However, sometimes you get lucky, and if you do, you’d better not blink. Well that is a very corny segue into a recent episode of Voyager that I saw. Blink of an Eye is about a planet who’s time passes at a much quicker rate than “normal” time.
Voyager witnesses the evolution of their humanoid race from cave dwellers to a civilization capable of firing anti-matter torpedos into space. I thought it was really neat that you could see the long term view as if you were playing a game of Civilization. While there were some sketchy moments (their race can change their metabolism from their time to normal time?), overall it was a neat idea and what I expect from a Star Trek series.
