Trackers a solid thriller, a little familiar in places, but done with enough skill to make it worth the investment. And it’s easy to forgive the odd cheesy exchange – “Remind me why we do this?” “Because it’s our job” – when the action is this good.

There’s enough action in Trackers to keep you interested. But the first episode is disjointed and confusing, and you may not have the patience to stay with the show as the stories start to come together.
