I completely disagree. The majority of changes have nothing to do with the internal monologues. They flat out change the plots and characters. We did not need all the Logain stuff in season 1. We did not need the Warder funeral. We did not need any of the Tar Valon stuff. It did not quicken or advance the plot of Eye of the World. Those items were sheer waste of space in an 8 episode season.
Also, there are plenty of books that can be largely relegated to an episode or two (Book 10 for instance). There are huge sections that can be cut out and have zero effect on the plot. Rafe chose to cut out the good sections and fill it with his fan fiction.
