Season five of the zombie apocalypse drama could be a make-or-break one. Last year’s offering was a big step down from the brilliance of series three, even though ratings in the US were higher than ever. This opener is being broadcast just a day after American viewers get to see it, and picks up the action at Terminus where last season’s cliffhanger finale had Rick and his cohorts captured by a group of armed hipsters. As if they didn’t have enough to deal with already.
This channel doesn’t get too many viewers on this side of the pond, but perhaps the fact that it’s the first to show this much-hyped American show will draw some Irish eyes. Set in Batman’s home city years before the arrival of the caped crusader, the high-budget affair delves into the origins of that popular superhero and some of his foes. Familiar faces in the cast include Sean Pertwee and Jada Pinkett Smith, and those who don’t have access to the British broadcaster will get to see it on RTÉ 2 at some stage.
