I have another example of the show dumbing down the story. On the map that Jorah is looking at near :30 into the episode it completely omits Slaver's Bay, Valryia, and the west coast of Essos. It shows Meereen directly across the Narrow Sea from King's Landing. Part of the reason for Dany being stuck in Meereen is because of the vast distance back to Westeros. She doesn't have the ships to go by sea and can't risk the long march on the Demon Road. Again, are we too dumb to be able to comprehend distances or a sense of a large world?
