Heh. Most people think the show started sucking after it's 1st season, when any attempt at realism went right out the window. And while I enjoyed Michael Ironside's preformance in the 3rd season, that wasn't enough to compensate for the suckitude of the rest of the show.
Seriously, even the second season was bad, especially after they found that ancient alien shiop on the seafloor bearing the message that "technolegy is death", then the entire sub got abducted by an alien spaceship to fight a war on an alien "waterworld"
