National Treasure: Kiri

There was much to like about this four-part series, but I'm afraid the last episode left me thinking the whole thing had run out of steam.

Brilliant performances by Sarah Lancashire as you might expect, and Stephen Mackintosh also showing his skill as a mature actor (I'm old enough to remember him when he was a schoolboy alongside Adrian Mole). The supporting cast also added weight to this tough drama.

I also loved the photography - in fact the atmosphere of the series was beautifully stylish, without it disappearing up its own backside.

However, I'll be honest and say I like my crime dramas to have decent endings, where the loose threads are neatly tied together and nothing is left in doubt. Everybody likes to see the culprit meet their comeuppance but this left one feeling the writer wasn't being clever in the way they drew the series to a conclusion, they were just being lazy.

The art of storytelling is really simple. A solid beginning, an exciting middle, with twists and turns along the way, and a brilliant ending, perhaps with some surprises. Certainly 9 out of 10 for the first two, but a disappointing 5 out of 10 for the finale.
