Im still in the category of, "Its Overrated". Im not even happy with some of the arguments presented as to why its not.
"Its reputation proceed's it", isnt a valid excuse for being a porno. Even Southpark did an episode to make fun of this. Children will still watch and see it. It doesnt stop kids from playing violent/sexual video games, and it certainly wont stop them from just opening a webpage and watching it on any number of devices in the house.
And then the argument for how you aren't expected to know every character by heart. "You aren't expected to know them all, but when someone actually turns out to be important you should know about them". The argument sort of contradicts itself, that you dont have to know everyone, but you have to know everyone.
Following that, the Red Wedding argument. "All these dying characters haven't done anything important to your knowledge. Except they are actually super important and can cause any number of absolutely terrible events can happen". This makes them important, but the show itself never really puts weight on it, and its compounded by the fact that you might not recognize half of their names unless you opened a wiki.
Im not saying Game of Thrones is bad. But if some of the problems with it are more "The failings of TV as a medium", but i dont see that as a real excuse. They couldnt focus on a smaller cast? Or cut the story into segments and follow smaller groups at a time? Episodes 1-10 follow 10 people, episodes 10-20 follow 10 different people, so on and so forth. Its overwhelming because they're trying to cover everything at once. And while this is one of the failings of TV as a medium, its also a failing of the director and script writers to not make it fit the medium itself.
Its a decent show with some good intrigue, but its still overrated for what it is. It has its problems, like a lot of shows, but its these problems fans constantly try to excuse.(like the consistent pacing problems because "So what? People do things and you have to deal with it!" Seriously, how is that even an argument? If i made a TV show about Nazi Walruses that was 29 minutes of talking about jewish fish in monotone voices, followed 60 seconds of pure explosions, would that be proper pacing? "Theyre walrus, and this is what they do until one of them causes explosions, so deal with it!" No, that doesnt excuse poor pacing. Again, this could be a "failing of TV as a medium", but its still up to the writers and directors to make it FIT THE MEDIUM, just like the writers and directors of the LoTR's movies made them fit the medium of Theater)
Im not saying you cant enjoy it, or that i dont enjoy it. But its still overrated, and overhyped to hell.
