J.R.R. Tolkien's captivating world-building has etched The Lord of the Rings as one of the most impressive fantasy franchises ever to grace all forms of media. The exceptional culmination of Tolkien's lore into two three-part movie series and an ongoing TV series is a true form of the fantasy genre that is still enjoyed after more than two decades. Most of Tolkien's cinematic adaptations have focused on the Second and Third Ages. These were troubling times as both ages have been plagued by Sauron's darkness in one way or the other. Fans must know the events of the Third Age because these years are covered in The Lord of the Rings Trilogy.
