Then there's "original broadcast order," in which you watch episodes 0, 1, 2, 7, 3, 9, 8, 10, 13, 4, 12, 11, 5, and 6. In that order. Then you watch season two as presented. This is more complicated than watching chronologically. It also isn't technically original broadcast order for season two, as season two was first shown during a chronological reshowing of season one. Yeah, it's that kind of show.
This is the best way - if you watch chronologically, the series ends on an calm anti-climax instead of a grand finale, and all the surprising things that get thrown at you cease to be surprising because most of them were explained before. And, depending on where you get the show from, the episodes might already be put in this order anyway.
