I could only stomach part of the first series, and I found the acting to vary between the okay (Davalos was fine) and the wooden (the male lead) to the wildly hammy (I mean god love him but Sewell just rips chunks out of the scenery), and the writing/dialogue was consistently dubious, as was the pacing and storytelling.
It’s visually very stylish, though.
It’s very superficial, I would suggest. If one idly and without much consideration thinks “what would a Nazi society have been like?”, one might come up with High Castle’s vision (and no blaming Dick, the TV show massively expands on the scant details from his book - which isn’t even very long).
But historians who’ve examined the where the Nazis were going have actually ridiculed visions of their society as likely to be clean/streamlined/futuristic, etc. Based on how the Nazis actually behaved in terms of resource usage, constant, violent internal conflict, social ordering, priorities and so on, it’s likely their society, had it somehow survived WW2* would have been stuck in permanent rationing (for decades) and been extremely inefficient, probably more closely resembling East Germany post-real-world WW2 than anything else. A massively inefficient, concrete-covered, ultra-bureaucratic, extremely oppressive mess. They also had a huge problem in that, like the Soviets under Stalin, they frequently rejected correct and demonstrable scientific theories which didn’t fit their ideology (as an aside, genetics would have been a massive car-crash for them, and probably brought down their society entirely - no ubermensch for them - they’d have been too busy shooting each other for being possibly-Jewish). It was a worse problem for them because it was purely ideological (not really to do with Hitler - he was responsible for plenty of other bad ideas though), whereas with the Soviets it was partly ideological, but mostly Stalin personally (and his completely out-of-control ego).
I feel like High Castle romanticizes them a bit, honestly.
But that’s beside the point. The real problem High Castle has is that it is extremely boring. It’s poorly-paced, the story is poorly-told, none of the characters are particularly likable or memorable, and as a result I found it a chore to watch. Maybe it improved in the third season. I’ve heard it certainly did not in the second.
For my money it’s representative of a troubling trend in fairly big-budget TV shows, which is to have shows which have nothing really to say, and aren’t even exciting or fun, but have such high production values and so much visual style that people seem to like them solely on that front.
What I’m saying I guess is it’s like a deeply mediocre computer game with great graphics, except a TV show (yeah I’m looking at you too Westworld, though you’re more like a 7/10 computer game with even better graphics).
- = (a virtual impossibility given the simple maths of their situation - even had Britain surrendered and the US stayed out of things, the Soviets would likely have won by 1948, especially as the Nazis would literally never have discovered nukes, having actively rejected the correct path and aggressively pursed a wrong one - though of course High Castle posits something weirder so that doesn’t apply)
She was also never “original Good Girl™” in the comics, though, that’s a cartoon thing, she’s always been a bit out-of-hand. She’s actually been nuts a couple of times, too, not just in the New 52 (hardly unusual for a superhero who has been around for nearly 40 years - your judgement seems, from what you’re saying, to be based on 90% Teen Titans cartoon and 10% DC comics from the early '00s).
Spoilers but it turns out there is a very good reason for her behaviour in Titans, it’s just the show giving you the impression she’s a ruthless psycho at the beginning, definitely playing on what happened with the New 52 version - it’s rather similar.
