Comic-Con is the time to promote big genre projects, and few are as big as The Lord of the Rings: The Rings of Power. Amazon's prequel to J.R.R. Tolkien's fantasy masterpiece isn't lacking in ambition. It aims to tell an epic tale about the events in the Second Age of Middle-earth, pouring hundreds of millions of dollars into production to accomplish that goal. Needless to say, a lot is riding on the show's success.
