Well yeah, that pretty much is what you said, but nevermind.
It's a TV show so obvioulsy things are gonna happen that are out of the writers' control, so they're forced to change stuff. I must admit on the whole I'm pleased the way they handled these instances though, especially with Eko, because even if they didn't want him to leave they gave his character a great send off.
And I must say I like the 6 season limit thing. It's running out of steam, yeah, but at least it wasn't cancelled. I'm still pissed off about Carnivale being killed off because it was pretty much the best TV show ever.
