Nothing comes to close to GoT's spectacle. Like, I'd say that cinematography and even production values are not the same thing as spectacle. Westworld has amazing production values, incredibly good looking sets, great cgi, just top quality all around, but does it have 1 hour long battle scenes? No. Does it have a dragon burning an entire city down? No.
I highly doubt that anything will even come close anytime soon.
