What makes it different from others?

A lot of fun.

There's a more than satisfactory amount of boom-boom in the movie's trim running time.

Just intense enough to provide a much-needed diversion, just lightweight enough to make you forget about it soon after it’s over. It’s not exactly “good,” per se, but it does what it sets out to do in terms of putting us on edge, which makes it … successful?

It's very rarely that a dramatisation of a novel outstrips it in intensity, but this TV adaption surprised me. Joanna Trollope's novel, like all her novels in my opinion (and I've read them all to date) was much gentler than the series suggests. Particularly strong were the child actors, showing the viewer with very few words how traumatic their parents' troubles were for them. Watching this, I was tempted to think that the children were the strong ones, and the adults could have done with standing in a corner for a while!The adult cast is also strong, with particular mention of Denis Lawson - aging beautifully!!! - as the father ground down by the manipulating of his grown daughter, and also Lesley Manville as the very distressed and disturbed Nadine. Also worth a mention is Emilia Fox as Dale, the manipulative, but very childlike daughter of Tom, the Denis Lawson character. I almost didn't give her special mention because I've never yet seen a performance of hers which is anything other than extrordinary!This is a very modern tale well told. A must-see for all who enjoy people-stories.
