Yeah, that is what I meant. It is dated for fantasy targeted at adults (which LOTR is compared to the Hobbit). Nowadays adults want flawed heroes, and complicated villains. And we can deal with killing a main character or having a bad guy win every now and then. For kids you have to keep things simple.
Basically Game of Thrones dated the LOTR movies in the adult fantasy world the same way the Battlestar Galactica reboot exposed almost all of the 90's space operas as over-the-top cheese. I couldn't even imagine following a new space opera today that wasn't dirty or gritty, just like I couldn't believe I was sitting there in the third Hobbit movie watching our "heroes" slay yet another paper mache Orc.
They do? People say that but a lot of characters that people love are simplistic as hell (at least as simplistic as LotR characters). LotR is a very flawed story absolutely, but let's stop pretending that characters now are that deep. Just because they cuss and fuck doesn't make them deeper. In fact, I'd say if you're complaining about the simplistic characters of LotR you kinda missed a major point of the overall story, which is that ones like the elves were effectively demigods and left and that flawed men inherited the world. Yes Aragorn took over as king (and married the elven princess) and men proved their valor in the end, but, they made it very clear that things have changed and that wouldn't always be good (hell the Hobbits return home to the Shire being turned into a wasteland by Sauraman and have to fight to take it back). Isildur, Boromir, Faramir, Theoden, and Eowyn are every bit as deep as most of the characters we have now (and a lot of the Game of Thrones ones). Don't get me wrong, LotR is a deeply flawed story and plenty of the characters are one dimensional archetypes to a t (which considering it in many ways created those archetypes though), but I feel like people are just deluding themselves if they think things are really any better now just because characters are "deeper" (which often just means given a dark backstory to justify them being psychopaths like Walter White). They might have more explanation for their actions and those might be more realistic (although personally for me the way that Game of Thrones mixes the fantasy stuff with that gritty realism, I think is actually pretty terrible and makes the overall result worse; I think it would be a much better if they cut out the fantasy zombies and dragons stuff; I feel like we're getting a really long drawn out situation like the ghost army from LotR, or the battle of five armies from the end of Hobbit).
The Hobbit movies sucked for a different reason (seriously, there are behind the scenes stuff where Peter Jackson straight up goes "I don't know what is happening"; the Hobbit got ruined because Del Toro dropped out and then Jackson had to rush out something without proper thought or planning). Del Toro's vision was really interesting and I think would have added real depth to the story. It also would have contrasted that with whimsical that was often lacking (even in the LotR, but especially in the Hobbit) which made it great (Peter Jackson's had that, in fact that opening when the dwarves show up and then do the song, and then we basically got little if any more of that).
