I should not be asking here, but does Seaquest has on outstanding season worth watching?
Are there any aliens on Seaquest?
3 seasons. Yes there are aliens. A trip into space with their submarine, because of relativity, they were gone for hours yet it was a ten year journey which completely changed the tone of the planet from first stage TNG happy to the middle of DS9 paranoid between season 2 and three.
There is also time travel.
