I quote Edward Lear, because this series, with its beautiful shots of the Shetland coastline, was indeed way out at sea, but in a sieve, absolutely all at sea, trying to somehow present a plot with even more holes in it than that kitchen device.
I actually lost count of the times I thought "surely not!" and "this is way too silly!"
And so we finally got to reach the very end of this rambling series, with as many scattered corpses as Midsomer. Absolutely everything appears to be predicated upon a whole swathe of utterly random and grossly unlikely coincidences, and all these improbabilities easily morphing into impossibilities. I think I need to list them one by one under 'goofs', but only if I can be bothered. I don't think I can.
We have very much enjoyed 'Shetland' in the past, but this, which looks like it will be the final series, just went way too far in the 'suspend disbelief' stakes.
The acting from the central characters was as good as ever, but it must have been very hard for them trying to work with this disaster zone of a plot.
Good acting, crap plot, makes 6/10, and that's for the whole series.
