The fuck did you expect out of a FUCKING COMIC BOOK lol?
The elaborate writings of a George R. R. Martin?
Its a damn comic book & its a better comic than about 90% of what comes out of all 3 of the major comic multiverses.
I mean I am not saying I disagree with your assessment but I also don't exactly set the literary content of a COMIC to be anything above what it should be.. a fucking comic book
Its a TV show based off a comic book & its pretty fucking good.. Show me another comic book TV show that has you waiting for the next episode to come out.. name one
