You’re the first person I’ve known to not like the Man in the High Castle. Do you dislike other PK Dick stories?
Just to even further expand your horizons, I also think the TV Man in the High Castle is terrible. So badly written I could barely make it through the few episodes I did. But then, when it comes to filmed entertainment, I have opinions.
As for PKD, I've read every one of his very many novels. I love him. Man in the High Castle is one of his best.
Meanwhile, the three part British show A Very English Scandal is great. Hugh Grant is better than he's ever been, Ben Whishaw is fantastic, it's written by Russell Davies (the writer behind the the first 4 seasons of the modern Doctor Who, and much else in British television), and directed by Stephen Frears, a long time film director you might best know from The Grifters and High Fidelity.
