Masi Oka (Heroes) provides extra comedy as the hyper-intelligent medical examiner Max Bergman, whose adorable quirks seem to put him somewhere on the Asperger's-syndrome spectrum.

If it were any other remake, we'd probably whinge that it falls short of the original. But it's Hawaii, brah, and in the jurisdiction of sun, surf and beach-babes, we find ourselves taking it easy and having fun - just like the islanders do. Of course, for the Five-O team, there is plenty of action and a few interesting story arcs based on the collective memory of Pearl Harbor, the tension between island communities and McGarrett's investigation into his late policeman father's last case.

Playing it irreverent isn't a stretch for Tim Roth (Reservoir Dogs, The Incredible Hulk). But the British actor takes it to a new level as Dr Cal Lightman in Lie to Me (Fox, two new episodes every Sunday at 8.30pm). So much so that co-stars have given his body language its own name - the Lightman Lean.

The posture, complete with a lurch and a squint, seems to say, 'I dare you to lie to me'. It certainly seems to bring out the liar in most suspects in the fictional world of 'truth science'.

In the second season, we see the inscrutable scientist's more human side through his evolving relationship with his daughter. But he still treats his young proteges as punch bags, even as they break case after case of truth obstruction by political candidates and dissociative-identity-disorder patients alike.

Roth proves that if you've got the attitude, you don't need muscle to play the alpha male.
