It seemed like it is going to be like the new BSG - miss one episode and then you're screwed for the rest of the season.
Eh, I doubt it. BSG has some long term stuff, but just about anything of any real magnitude was either a) recaptured in the "Previously, on BSG" notes at the beginning, b) resolved quickly enough to that it didn't matter any more or c) simply reiterated, clarified, or expanded upon in the later episodes.
Folks basically said that about LOST, how you had to watch it from the beginning, etc. And it seems to be that WAS the hook for LOST. All the arcane made up BS that they were spewing that folks that folks tried to provide order to.
Well, frankly, since everyone talked that up, I never watched the show. And after hearing about the ending, I'm glad I didn't. Since it basically was mostly BS, as I understand it.
There's value to those who wait for the end of season DVD, at least then you have a good idea if they're going to continue the show, particularly if they left it at some silly cliffhanger, or just pulling the plug as Fox is wont to do.
But, I think most of the show execs are realizing that detailed, long drawn story arcs DO lose people, and they simply can't afford it. Meta arcs are fine, or overlapping storylines that span a few episodes. But the whole "miss two episodes and you may as well give up", that's really counter productive for the studios.
Episodes should be able to stand on their own, like watching Firefly without perhaps understand the whole meta arc about River (which arguably is what the show is all about, the crew, ship and adventures are simply mechanics to reveal more about River and who she is).
Terra Nova is going to be light weight enough that you might be a little confused after coming back, but give it another week and it will likely all fall in to place again. If you can only catch every 3rd episode, then I hope you like rampaging dinosaurs...
