My point is that Game of Thrones goes for a more epic scope with its episode structure while Doctor Who's episodes, well, don't.
It's always been epic. Season 20 didn't cost shit but there was Arc of Infinity, Snakedance, Mawdryn Undead etc.
We are watching for the content, right?
Not that they don't fly all around world these days to make the episodes and build tons of sets like the new Tardis set and special effects like the new Cybermen.
