i can think of a few things. for starters, being alive.
the show is definitely one of my favs. effing boats sinking, dudes going overboards and being rescued by other boats, empty survival suits floating on the water (damn), guys getting slammed by rogue waves, breaking ice 2 feet thick off of the boat, having pulmonary emobilisms while captaining the ship...(and that was just last season)
come on y'all, this show is the shit.
sometime i watch an exciting movie and i say to myself afterwards, "i wish i was james bond, or a race car driver, or a fighter pilot". after i watch this show im like "damn, im a pussy, cause theres no way im doing that shit."
