Look, may I point out that the series producer, Nigel Farrell, was dying during the making of that series and, indeed, did so not long after finishing it? His was the voice you hear putting the camera's questions, as it were. I knew him, he was a really nice bloke who fell in love with Barra while he was there.
He could only show what goes on within the church. He didn't choose the people or, indeed, influence what happened. It's only meant to be a reflection of what goes on. I do have some small idea what's in the rest of the series and would suggest that keeping an eye on it will be worth doing. It's not a soap, but there is some interesting stuff to come, I believe.
Cheers.
