The best way I can describe it is... take 11 standalone X-Files episodes that have nothing to do with each other, then put an episode at the beginning and an episode at the end that states everything is connected and leading to something bigger.
That's a bit of hyperbole since there is connective tissue with Debris, but you get the general idea. There's a lot of "part of this episode is interesting but who cares" going on.
Reminds me of season 1 of Fringe, which was the least effective season because there was so little rhyme or reason apparent to the weird cases of the week, with the explanations not really coming along until late, and the rich mythology arc that made the series so effective not really coming into focus until the second season. Indeed, seasons 4 & 5 made season 1 better in retrospect by revisiting some of its random weirdness and connecting it more fully to the arc.
So I presume the intention here was to eventually begin tying it all together in the back nine or in a second season, if it had gotten either. A lot of these shows on the main networks die young because they start out with such slow burns and lose their audiences before they get around to kicking their arcs into gear.
