Pennyworth (Batman TV spin-off: season 2 trailer).
Pennyworth moves into the second season of what it imagines the Batman universe swinging-UK of the 1960s as, and ^%$$£, is it bleak!
Britain is fighting a civil war between a bunch of freaky fascists on one side, and the Queen’s royalists on the other, and Batman’s butler, Alfred Pennyworth, currently running a black-market club, is in search of a way out to the USA before England burns to the ground.
A bit like the Ipcress Files meets The Man in the High Castle with added superheroes and villains, because that concept wasn’t mad enough to start with!
