First, I do get a little tired of Alan Moore saying that he wishes comics companies would stop exploiting properties he created that he doesn’t own, or that he co-owns. On the other hand, he has his wishes, and the media keeps asking him what he thinks of the latest project based on his work, so what do they expect him to say? “Oh gee, you’ve worn me down, so I’ve decided that it’s great they’re doing this.” So I think people who complain about Alan Moore complaining doth protest too much. As long as people keep doing new projects based on his work we’re going to keep hearing him complain about them, so we just have to accept that and move on.
On the other hand, it’s hard to imagine a less-necessary set of books than prequels to Watchmen. It was a gorgeous and influential book which was complete unto itself, and which is tightly tied to the creators who made it (Alan Moore and Dave Gibbons). Moreover, it pretty much plumbed the depths of all the major characters, and what was left unsaid was left so deliberately. Any prequels I think would only be interesting to the extent that they inform a new reading of the original book, but since Moore and Gibbons aren’t doing the prequels, I expect they’ll feel superfluous.
It’s strange to me that DC would do prequels to the series, rather than a sequel, since building something new on top of the original might genuinely move the book forward. But doing prequels just seems like a cynical effort to squeeze some more money out of the property – cynical because it indicates that DC is too timid to do anything daring.
Which is ironic because, as Moore has said, the whole point of Watchmen was to do new things with the medium (graphic novels) and the genre (superheroes). You can argue to what extent they succeeded in being truly innovative, but the book clearly greatly influenced comic books for years after it was published. Going back and further rooting around in the backstory of its milieu seems contrary to the spirit of the book itself – and thus all the more cynical.
But in pop culture all old fads end up coming back and being revisited or reworked eventually. Sometimes they’re good, sometimes they’re bad, sometimes they’re fresh, and sometimes they’re stale. The only way this project is different from DC relaunching the Doom Patrol/the Teen Titans/the Suicide Squad one more time is that it has Alan Moore complaining about it.
Just remember: The great thing about literature (graphic or otherwise) is this: Regardless of whether or not Before Watchmen ends up being a cheap knock-off of the original, we can always go back and enjoy the original. Considering how many superhero comics have devolved into a serpent swallowing its own tail, that’s an important fact to remember.
