This story follows a modern-day scientist who accidentally discovers time travel and is stuck in the 1940s, leading to an alternate history in which the Cold War is an arms race to develop time travel. Time travel has thought out mechanics and long-lasting personal consequences, which several episodes explore the logistics and morality of, including government conspiracies and scientific experimentation. ars Paradoxica explores people searching for meaning, attempting to fix mistakes, and corruption of power. The characters, especially the main character (Sally) and a supporting character (Esther) are complex and well-acted, though I had trouble distinguising a couple of the male voices in season 1. I'm also not 100% sold on how the framing device comes together in the end, but that's a bit of a nitpick. The story has dramatic moments and stakes, as well as some levity and an overall bittersweet tone.
