Prime Video’s 2015 adaptation of Philip K. Dick’s The Man in the High Castleimagines what America would be like if the Nazis won World War II by nuking Washington, DC, and invading the country. While the series found lots of dramatic and poignant ways to play with that premise over the course of four seasons, HBO’s spin on World War II alt-history was even better because it relied on far subtler changes. It’s also only six episodes, making it the perfect weekend binge.
