I must admit this is right up my alley. I'm a hardcore Whovian, Trekkie, and lover of both comics-turned-film (Marvel) period drama (think Downton Abbey). I believe it's a strange combination; I've never met anyone who enjoys all of these genres. Until now, maybe? This series is the exquisitely crafted intersection of all of them. It weaves together the lived and experiences of 4 people, scattered across time in London. Each time period is crafted, from costumes to music, with care and precision. It's both hopeful and tragic, and so compelling that I'm about to rewatch the entire series. If this is read by anyone affiliated in any way with its creation, know that you are brilliant. And your work is loved.
