As a weaving of four stories this works well. The sets are great and even the thirty years into the future thread wasn't too out there.
There are a few good characters, some good light and shade and some that develop nicely as the series progresses.
Everything starts with a body being discovered in a lane in London and develops with four different time lines, Victorian, World War Two, present day and thirty years into the future. At first there is a lovely kind of what-is-going-on feel to the story, but come the middle of it, you realise that it's just the same thing that's been done so many times in so many other sci-fi programmes and films that it becomes more and more disappointing and eventually so incredibly and sadly predictable.
