In doing some "research", I had read that the producers had pre-plotted out the major events of the series early on. Is this not the case?
I don't know but I don't believe it for a second.
And it wouldn't be the first time where a producer would try to claim there being greater fore-thought go into plotting than there actually was. That's good to know as another show that this happened to was Prison Break which was remarkable at the beginning but to where things ended up in season 4, you have to ask "how the hell did we ever get here
I don't mind a show having some significant growth and change in focus if it is believable and shows a clear progression (i.e. Lost, Babylon 5). But if it seems like something totally out of right-field that appears to have just gradually meandered far from its intended focus, as in Prison Break, that can be a bit disappointing.
