I said pretty much the same in a comment above, but I’m not against filler, or bottle episodes, though I may have come off that way. I’m just against bad filler, stuff that would have never made it into a show if there was no predetermined season lengths. In a perfect world, it would be great if stories could be chosen simply because they were great stories. I’d like to know that something like the Fly episode of Breaking Bad would could still be filmed just because the show runners thought it was a great story, and not because they had a make a certain number of episodes and needed to save some money on one episode so they could spend more on another.
