Well, you probably won't actually be able to, but if you really are opposed to the Watchmen prequel, you can always take a stand and sign the petition to get the
newly proposed comic book stopped before it starts.
While there's always a good chance the
publication won't get completed, something tells me a petition with less than 300 signatures won't have much to do with it.
