How do you turn a tight 4 episode thriller into a flabby mess?
You add as much sentimental melodrama as you think the audience can just about stomach and then...
...add some more in just in case you underestimated.
And to make sure, you intertwine two plots that almost never end - one is extended by...
...OK, I'll say it, "it's a miracle!"
Great central concept - utterly abysmal screenplay and execution.
