So it’s confirmed, the new Amazon Tolkien series will be set during the Second Age. This seems like a fine choice, since some of the characters that we know and “love,” such as Sauron, Galadriel, and Elrond, will be major players, and the framework for the Third Age which is the backdrop that we’re familiar with will be set.
Additionally, as noted in the reactions, the fact that much of the action could take place on Numenor is probably a good thing for character development and dramatic tension. Numenor is the byword for hubris in Tolkien’s legendarium and opens up a path for a more complex and realistic take on character development than may have been possible during the more mythological First Age.
And of course, the series could culminate in a set-piece battle to end all battles.
