Even with B5, it didn't follow its original 5-year plan. Summaries from the supplementary materials for the scriptbooks demonstrates that was originally planned was very different from the actual product. Sinclair's actor's departure seemingly changed the show to the point that the stuff with the Vorlons/Shadows, the Minbari and the ending were all changed. Mapping out a show years in advance is difficult because of changing bts stuff like writers/actors leaving the show or suddenly having to retool because of ratings/execs. No plan survives intact especially in a chaotic environment of television production.
To be like Babylon 5, you need to cram a 2 season story arc into one because you fear being cancelled, then get further seasons you have no more material for. You also need a spinoff which the network heads don't want and do everything in their power to kill it while it's on air.
And then, after five years of hosting their own official podcast where they would answer fan questions and always encouraged their audience to pay attention to the mysteries, after the show had ended, they claimed the show was never really about the mysteries, it was all about the characters.
What really bugs me with "Lost" is that the producers had willfully negotiated a set end date with the network halfway through season 3 (the show ended with season 6, as planned) specifically so they could plan out the plot for the remainder of the show. Then... the plot wasn't resolved properly.
By then I had lost interest in arc TV shows, I followed a few and got the impression they were just making them up as they went along. Seemed to be a trend starting with new Galactica and Lost though in actuality began with The X Files and has become a trope called 'The Chris Carter Effect'.
Hey everybody! I wanted to announce that Sarahthecutevixen is our newest addition to the Allspark staff. She's primarily looking over discord stuff, but I wanted to make sure she got a welcome over here as well.
