I really wanted to like the adaption of "The Man in the High Castle", but was dissapointed it went in directions greatly different than the book. One example is "The Grasshopper Lies Heavy". It is is no longer a book, but a 16mm movie filled with images of the Allies winning WWII including scenes from VE and VJ day. How did this movie physically cross from our reality to their reality? As a book, the alternate reality was about ideas and imagination, not a physical reality to be escaped to. This could lead the series into well worn SciFi time-travel and alternate universe trope that wasn't what the PKD story is about.
I thought the visuals and atmosphere of the show were good, but the characters seemed to bland vanilla versions of the rich and colorful characters in the PKD source material.
If Amazon picks it up, I'll give it more of a chance, but I didn't enjoy the show as much as I wanted to. I remembet it taking me a little while to get into the book so perhaps I have to do the same with this adaption.
