1. Amazon can explore parts of Middle-earth the Peter Jackson’s movies couldn’t get to
As great as Peter Jackson’s movies were (and they were great), large parts of the source material were cut in order to save viewers from seven-hour movies experiences. Gandalf might have raced from one end of the continent to the other fast enough to make Littlefinger’s head spin, but Middle-earth is more than just Rohan, Gondor and the Shire. There were entire regions of the continent left unexplored by Peter Jackson, and even by J.R.R. Tolkien himself.
That gives Amazon a lot of room to play. Little is written about the North and Southeast portions of Middle-earth. Who’s to say there aren’t tropical jungles or deserts out there somewhere? What kind of creatures or people might be lurking in such new and wonderful habitats? The possibilities are endless, and as long as Amazon doesn’t take it too far, these regions could provide all kinds of adventures for our heroes (and villains).
Much as we enjoyed the Fellowship’s adventures through the Misty Mountains or the Battle of Pellenor Fields, we’d love to see a small Elvish colony living in a jungle somewhere, fighting off some orc-monkey hybrids. Or maybe not that exactly, but you get the idea. Sometimes all it takes is a change of scenery.
