I started watching the new Watchmen series on HBO when it debut, however the Netflix age of binging may have gotten to me because I found waiting a week for a new episode lent to distractions. Thus, after a couple of episodes, I slipped away and came back when the season finished. Then I watched it in a couple of evenings.
If you're at all familiar, you'll know that the series ties into the Watchmen movie from 2009, which in turn was based on a comic book series of the same name from 1986-87. Though the new series is a sequel, largely set several decades after the movie's time period, the series also frequently jumps into the past, to the very start of masked vigilantes and even before that. The new series also introduces mostly new characters, and while their lives and the world acknowledge the characters from the movie, they are distinct, and the flashbacks serve more to develop the current characters than anything else.
I found the original movie, which was my first experience with the Watchmen universe, to be a compelling look at a more human and faulted version of superheroes. Not your Superman, or Batman, but truly multifaceted people. I love that. The villains aren't evil strawmen. The heroes aren't angelic. They're all just people, flawed, sometimes selfish, sometimes generous, and often egotistical as would be natural from having exceptional powers... people.
The series does an excellent job of keeping that theme alive while introducing and developing new, distinct, fascinating characters, taking them and us viewers on exciting and action-filled stories, and still ties it all into the source material. The story draws from the original, feeds into the original through flashbacks, and adds layers to it as well.
This is way more than just a sequel series. It doesn't just continue the story; it builds to new heights on it's back. I imagine that was the goal going in, and I say they nailed it, plus the acting is fantastic.
Do yourself a favor, go back and watch the 2009 movie, then dig in on the 2019 series. Otherwise, who's watching the Watchmen?
