But what about the consistency of the middle earth...
Brutaly honest?
In the end nothing would change ... :-/
People who didnt read the books, would never complain since they would not even notice that something is off.
And people who did read the books, would have "yet another" topic to complain about ... but there is many of them allready, so that hardly can be called a change.
I think if the movies made all of Middle-Earth fit into the size of Disneyland, they would get some flak from more than just hardcore fans of the books. Picture the battle of Gondor with only room for about a dozen orcs outside the gates, with Rivendell, Moria, Rohan and Mt. Doom all in the same shot.
The best part would be when they light the signal fires to request aid from Rohan, and the signal fires are spaced 10 feet apart, with the final destination within shouting distance. The riders of Rohan wouldn't have enough space to get to a full gallop before they were at the Gates of Gondor.
