On the plus side, it has an engaging narrative and some really interesting, strong female characters. It draws you in, and once you start watching, it’s hard to stop. You get really invested in the characters.
On the minus side, there is an excessive amount of sex, nudity, and extremely graphic violence, as well as a nihilistic world view. It’s not about good versus evil, but about the strong versus the weak. It has few pure-hearted characters, and the ones it does have mostly die or meet other bad ends. It’s kind of the opposite of JRR Tolkien, and it’s decidedly not very Catholic. I would guess that if it were a movie, it would be given either an L or an O rating
As a former GOT fan, I’d say that the nihilism is certainly part of the show, but not quite the case in the books the show is based on. The problem, will one of the problems, with the show is that it really has taken the original idea to subvert the cliché of “the good guys always win, even against impossible odds”, and run with It to such an extreme, that they now have a new cliché: “the bad guys always win, even against impossible odds”.
The villain, Ramsay Snow, has essentially been portrayed as an untouchable genius who can run into battle bare chested and not suffer a scratch, defeat a whole army with just 20 men, etc. As opposed to villains from earlier in the show, who actually were just as likely to “die or meet other bad ends” as the “good guys”. Indeed, one of the reasons (I assume) the show has turned Ramsay into such a super-villain, is because most of the other big bads were already killed off.
Anyway, I’d say that at this point, even many people who don’t mind a little sex and nudity, have abandoned the show because of other issues with it. An inordinate focus on not just sex, but sexual violence, and women being subjected to rape and sexual torture, to the point where the show has invented or amped out several such scenes that were not in the books.
Also, note that the books do have a lot of sex and rape and murder, BUT most of it is really not that explicitly spelled out and can be easily skimmed over in reading. The show used to be more subtle; there is a “Mongol-like horde engages in rape and pillage” scene from the first season, that doesn’t actually show any graphic rape scenes, but makes it obvious that rape is happening or about to happen.
But that’s not the case for a mostly made-up scene in S4, essentially the equivalent of a bunch of murderers and rapists escaping from jail and engaging in mayhem. A scene also mentioned in the books, but not in any detail. But the show portrayed random bad guys raping random women as just background detail – you couldn’t see their faces, hear their screams, or even get the sense that the women were suffering at all, and it seemed to be obviously there for titillation, though the director claimed they showed this scene to establish how evil the rapists were. The women do stand up for themselves later, but that scene really was the beginning of the end for me.
As for the role of the Faith; the theology of the Faith actually does have a surface resemblance to Christianity, the 7 gods are supposedly all manifestations of the same god, much like the Trinity. However, there is no Jesus figure, no salvific aspect to it. It’s
essentially an example of the “Crystal Dragon Jesus” trope, per the
TVTropes site:
Any fictional religion, such as those found in a Medieval European Fantasy, which possesses attributes stereotypically associated with Christianity (especially Roman Catholicism) — such as priestly vestments, nuns and their habits, confessionals, the designs of houses of worship, and crosses — but which centers on a deity other than the Christian God, like an animistic spirit or pagan-flavored god. Often there will be a Yahweh analog and/or a Satan analog but not a Jesus one
The Faith also has very little political power for most of the story, quite unlike the actual medieval Church. Unfortunately, the TV version of the Faith uprising essentially portrays them like a amalgam of ISIS and the Westboro Baptist Church. Religious fanatics carving stars into their foreheads (the 7 pointed star is the Faith version of the cross), burning down brothels and persecuting gays. (Though ironically, the TV show’s treatment of its major gay characters is very stereotypical.)
In the actual books, while the “High Sparrow” does punish one of the female characters in the same way as the show, he is motivated by much more than just rooting out sexual sin. He also is angry that the populace has been decimated by war, rape and pillage, and the uprising is more about people trying to defend themselves from the Gregor Cleganes of the world, than persecuting the Loras Tyrells.
He does find the Church hierarchy corrupt and complacent, but not just because they are entrapped in sexual sin, though that is part of it – the High Septon preceding him is not caught in a brothel as he is in the show, he’s assassinated. However, one of the candidates to replace him (the hierarchy equivalent of a Cardinal) IS caught in a brothel.
