Trigger Point tries hard, but almost ends up a damp squib

Among my sons' favourite expressions is one they use to dismiss anyone they feel is a little too enthusiastic, a little to eager to get on and do well.

"Oh, he's just a try hard," they say.

Which could just as easily apply to ITV's bomb squad drama Trigger Point (ITV, Sun/Mon, 9pm) as it could to a bookworm Year 10.

Now in its third series - so it must be doing something right - it really does put in 110 per cent to make every scene as thrilling, tense and nerve-shredding as possible.

Even when lead bomb squadder Lana 'Wash' Washington (Vicky McClure) is chatting about redundancy payouts with her parents, it ups the stakes by suggesting it's not for her parents to survive on - cue strained faces and clenched fists all round.

And it only gets worse when Lana and her team are dealing with actual bombs rather than metaphorical ones.

This new series saw the squad called out to a black cab left abandoned on waste ground.
