It’s easy to forget what last happened in the disappointingly dull Game of Thrones prequel two years ago. But the bloodiest naval battle in Westeros history – the Battle of the Gullet – actually kicks season three off with a bang. The Targaryen civil war finally gets into full gory swing, with Alicent (Olivia Cooke) and Rhaenyra (Emma D’Arcy) orchestrating their moves for the Iron Throne. Yes, there are still too many dislikable characters moping around, and it’s not a great sign when the only one you feel anything for is a fire-breathing dragon. But there’s no denying the wow factor of epic sword clashes like this one – and there are plenty more promised ahead. Plus added James Norton! Hollie Richardson
