I bet there are some folks on this list who remember Edge of Darkness from its original broadcast, and I wonder if you would give me your opinions on comparing SB to it. I cannot imagine anyone else but Marsden portraying Burnside, or anyone besides Peck portraying Inspector Craven. When I watch them, I do not have to suspend disbelief to get involved with the story.
Character development is a major strength of both productions.
I have spent years searching for information on EoD here in the States to no avail. And if you don't know what the devil I'm raving about, rent the thing when you have five hours to spare and let me know what you think.
