Looking at the reaction to this show from those who seemed to want instant gratification and the big reveal 45 minutes into episode 1, I suggest we all get together and send an open letter to TV producers around the world.
Dear TV producers
Please don't waste your time and money on shows that require patience and intelligence on the part of viewers. And don't bother producing shows that, like a classic novel, take time to build storylines.
Unfortunately, today's TV audiences have acquired Attention Deficit Disorder, and as such are unable to enjoy such programming. And it appears mainstream American networks have developed a similar lack of focus, witness the conscious decision by ABC (allegedly before Defying Gravity even premiered) to end the series just prior to the key episode that explained everything.
Please confine your creative output to shows that resolve their plotlines within a standard 45-minute timeslot, with the occasional (but, please, rare) two-part episode. Also, do not attempt to introduce any sort of story arc because you will not be able to resolve the arc in anyway that will please the audience, provided of course that the network allows your series to last long enough to get to that point.
Today's mass audiences simply are not ready for this sort of storytelling. If you must produce such programming, please confine it to the BBC in England, or similar broadcasters that have viewership demographics that are accustomed to such productions, or seek appropriate funding to produce the series specifically for DVD/BluRay and Internet release.
