Endeavor is so multi-layerd it took viewings to appreciate the nuance. The characters are all well developed, especially Shaun Evans whose subtle acting, is mesmerizing. The hands-off unspoken romance between he and Joan Thursday is excruciating. The cast, the beautiful cinematography, Oxford, and of course the stories. The operatic musical score fits so well. I love this series but because so much is underplayed and subtle, it took me a bit to warm up. Now it’s my favorite along with George Gently & Foyle’s War.
