Jason Momoa takes the lead role in this epic, violent dramatised story of Hawaiian history. Plus, a gripping five-part documentary series to mark 20 years since the horrific Gulf of Mexico storm

An epic history lesson, courtesy of the mountainous Jason Momoa. When we first meet Ka’iana (Momoa) he is something of a loner, capturing a shark with his bare hands and some rope. But he is coaxed back into armed service by the prophecy of an invasion that will lead to the unification of Hawaii. The drama is based on true events and great care has evidently been taken to present an authentic version of this undertold story. It is steeped in Polynesian cultural practices but it is also full of universal, action-adventure staples – namely, political machinations that periodically dissolve into prolonged outbreaks of expertly choreographed, frequently blood-curdling violence.

Twenty years have now passed since the horrifying events surrounding Hurricane Katrina, but this gripping series brings the trauma back to life in visceral style. What began as an appalling natural disaster soon became a national crisis then an outrage of governmental negligence and structural racism which came to embody – and irrevocably taint – the final years of George W Bush’s presidency. To watch the footage now is to be reminded of how close even the most seemingly advanced societies are to breakdown and chaos. Essential. PH
