Everything you said is impeccable, but I think that, at least, in the first three series, the writers were pursuing a consistent goal which they abandoned for some inexplicable reason. I'm working on a video to explain my point of view, but it's not done yet.

Great answer though, one of which I was expecting. Thanks Fimber.
