The main character is Westeros. There is nothing like this on television where every show have a starboy or stargirl to fall in love with.
The story is meant to be the star in this work.
This is what happens when you take a work that was actually and purposely meant to be unfilmable and try to put it on screen WHILE trying to stay as true to the source as possible.
The only thing I could recommend for allyuh is to go ahead and read the books. I know some people are loathe to do that with TV shows, and prefer to enjoy the medium as it is presented... but the fact that allyuh enjoy season 1 the most, shows me that the visual narrative was better for the casual fan when it was easier to follow with less characters and locations.
The fact is it may only get worse
depending on how much of the future story they keep. As a dedicated fan to the books and series I hope you all could hold on throughout. I expect quite a few ppl may become exhausted and stop following or may already have.
