It wasn't that 5 was bolted on...it was operating under a five-year plan, but they learned they were going to be cancelled after Season 4, so JMS cut out some subplots from the last two years' worth of story and ended the show a year early. But then it was picked up by another...well, not network, exactly, but another group of syndicated stations,* so JMS took the "deleted scenes" from the old 4 and 5 and made a new Season 5 out of them.Me, too. I was late to the party with the original and, frankly, it didn't live up to expectations (B-list actors, innovative -- but rather primitive -- special effects). And I still think that S5 was bolted on after they wrapped things up in S4, thinking they were getting canceled. Hopefully they go with a 5 x 10 for some tighter story-telling.
So basically, everything that he always intended for the show was in it, but Season 4 has part of the original plan for Season 4 and 5, and Season 5 has the rest.
*Actually, it WAS a network...TNT, after initially being on a "network" of syndicated stations arranged by Warner.
