Despite the jargon fetish, the dialogue has actually improved in series three. McClure is still the best thing in it, with Kerry Godliman as Sonya, the bomb data specialist, a close second. But the plot is no less preposterous. In fact, it is more so.

It keeps things just about the right side of plausible, even if McClure’s world-weary shtick is starting to feel tired.

Lana herself is never in any real danger, which somewhat dampens any sense of jeopardy.
