But in UK TV you don't necessarily get 6 great episodes. You just get 6 episodes. The same as you'll get 12 or 18 or 20 or 22 in the US. Even of the shows that I quite like, I cannot for a second convince myself that all 6 episodes have been equally good. It just doesn't happen often enough to be a factor. Certainly not often enough to be turned into an argument for purposefully producing less (6 instead of 12 as an example).

If this argument held water, every movie, at least every "first" movie if a series ends up being born, should be great. Or at least good. After all, there's only a single one to be made. Should be easy to come up with a one-off story.

Many shows simply need a few more episodes to elevate the entire show. Having more room can make every episode better, not necessarily worse. I guess I'm a glass half-full type of person.
