I should not be asking here, but does Seaquest has on outstanding season worth watching?
Are there any aliiens on Seaquest?
I'd say season 3 is the one most worth watching, because it's about what subs are best at (war), even though it's cancelled partway through. IIRC you can get season 3 on Netflix, but aside from that, you'll have to resort to piracy to get them since there's no season 3 DVD release.
There are aliens, but they're part of the problem with the show.
