*Alarm: This article contains all the spoilers from the finale of The Man In The High Castle so read on at your peril.

'It's unbearable to be able to walk through that door and glimpse all the people you could have been,' says Reichsmarschall John Smith, in the closing moments of The Man In The Loftier Castle's fourth and final flavor.

Information technology'southward easy to imagine a similar thought existence on a near-permanent loop within the minds of the show'due south writers as they plotted how the dark, sci-fi infused alt history serial was going to conclude. As a evidence that's ever played brilliantly with the idea of parallel universes, chiefly one where the Nazis and the Japanese won Globe War Two, there'south an space number of ways TMITHC could take gone. In the stop it settles on a gripping but flawed story that gives both viewers and characters resolution, if not redemption.

Last fourth dimension we were with Smith, resistance fighter Juliana Crain (Alexa Davalos) and co, a team of Nazi scientists had opened up a mysterious portal assuasive people to walk into alternate dimensions, like the one Japanese Trade Government minister Tagomi was able to send himself to using meditation. Juliana, meanwhile, had vanished into thin air, midway through beingness shot at by American soldier turned Nazi bigwig Smith.

Juliana's disappearance and that portal in the mountains of Pennsylvania suggested flavour 4 would treat usa to the sight of legions of Nazi storm troopers marching into our version of 1960s America, sparking a huge, heed-blowing inter-dimensional war. But instead it chooses to swap huge spectacle for smaller only equally devastating psychological battles.

Central to information technology all are Smith (played brilliantly by Rufus Sewell) and uncompromising Japanese undercover police chief Takeshi Kido (the every bit impressive Joel de la Fuente). Over its previous seasons, TMITHC slowly morphed from being nearly Juliana and the rebels' struggles against Smith and Kido, to being virtually Smith and Kido'southward struggles with their own consciences and behavior. Season iv is very much the culmination of that. But anyone hoping for redemption for either character has come to the wrong show.

Ever since Smith learned in season ane that his son Thomas suffered from an incurable congenital illness which would require him to be euthanised nether Reich police, it became apparent he harboured doubts over the rights and wrongs of the government he serves.

And, for a little while in season iv, information technology really does expect like he might decide to plough his dorsum on wheezing sometime Himmler and the Reich. His cursory trip through the portal into the parallel USA, a globe where Thomas is live and well, is the emotional highlight of the entire season. It's a tribute to Sewell's nuanced performance that this murderous Nazi's nonplussed reaction to being able to meet and talk to his dead son once again is genuinely moving.

That's not the merely moment of emotion for Smith during the trip. He'southward also blindsided by guilt and shame when his one-time army buddy Danny drops past to watch the baseball – the same Danny who, we learn, he betrayed dorsum in his universe, allowing him to be carted off to his death when he chooses not to join up with the victorious German army afterward the war.

In the cease, though, whatever feeling that he should to confront to his crimes is suffocated past Smith's desire to protect his own position in the Nazi hierarchy. Allowing him to undergo some kind of full-on Darth Vader-style last-minute change of heart would have provided the big Hollywood ending some fans might want but the show'due south decision to allow him proceed spiralling downwards is more truthful, and all the ameliorate for it.

Instead of dying a hero, Smith dies a conflicted human who can acknowledge to his emotionally-shattered wife Helen that his actions have been evil, but still doesn't have the chapters to change. He even denies Juliana the closure of putting a bullet in his skull by doing information technology himself.

Kido, too, spends much of season iv questioning himself and what he's done, just never quite beingness able to suspension free. It's non all the killing and torture he regrets – he can conveniently file all that under 'duty' – instead, it's the way he's treated his own son that really bugs him. The only redemption on offer for Kido comes from agreeing to repay his PTSD-suffering son'southward drugs debts past working for a Yakuza boss, a move he considers to exist securely shameful.

The only downside to this emphasis on Smith and Kido is that Juliana ends up feeling missing in action throughout much of the flavor. The time she spends in the parallel, peaceful U.s. – having done a Tagomi and transported herself there at the end of season three – feels similar a wasted opportunity. And while she does get to do a fair amount of bad guy butt kicking one time she returns to the American Reich, she remains a strangely peripheral figure, overshadowed much of the fourth dimension by her partner in criminal offence, Wyatt Price.

Season four also suffers from the absence of some the show's original and much loved protagonists. With Joe Blake and Frank Frink both existence brutally bumped off in season three, viewers have had enough of time to get used to the fact that they wouldn't be returning. But it'southward the lack of the charismatic Tagomi – in many ways the testify'south heart and soul – as well equally the gentle, loyal Ed, that hits home.

Despite being cardinal to the evidence for three series, Tagomi is assassinated inside the opening seconds of the first episode. Ed, meanwhile, last seen at the top of San Francisco'south Coit Tower, defiantly unfurling a huge imprint emblazoned with one of Frank'south protestation art works, doesn't merit a single mention. Not even from his old pal, antiques dealer Sheldon, who's yet gamely trying to flog Americana to wealthy Japanese folk.

There is still an atrocious lot to savor, though. The twists keep coming and the show understands the benefit of not getting besides caught up in the scientific discipline of beingness able to wander through the portal – choosing instead to use it sparingly. There's also the welcome introduction of the freedom-fighting Bell (Frances Turner), Elijah (Homeland'southward ClĂ© Bennett) and their comrades in San Francisco terrorist group the Blackness Communist Rebel, which adds a stirring new strand to the storyline.

Of course, flavor four was never really going to match up to the uncanny strangeness of the get-go series – we're much likewise familiar with this deeply unpleasant parallel globe now. But The Homo In The Castle just almost manages to maintain its power to shock, surprise and unsettle.

Not long earlier Smith finally gets his comeuppance, he tells Helen he doesn't know how to stop what he'southward doing. Thankfully for The Man In The High Castle, Amazon Studios does! While the evidence will certainly be missed – its impressive mash up of sci-fi, history and noir has made it unique in terms of contempo TV – it does feel like the correct time to call it a day.

Once more characters were given the ability to dimension hop, information technology diluted the evidence's impressive original air of claustrophobic, dystopian dread. It also hasn't helped that in this age of faux news, real life events have sometimes veered uncomfortably close to TMITHC's fiction since it debuted in 2015, again lessening its bear upon. That, added to the loss of those much-loved original characters, ways the dauntless decision to swiftly dispatch the show, Kido-style, is also the right decision.

Leaving things at this point – with the promise of a hopeful futurity for Juliana and the American people – seems similar the best way to bring this unnerving affiliate of alternative history to a close.
