I can open up my Watchmen book and have no different experience to what I would have had a month ago. If they incorporate and write great stories, then fantastic, I'm over the moon... if not then I'll just ignore them and be satisfied in the knowledge Watchmen is still there. I really see these types of stories no differently to any other character in that an abysmal Batman story has never affected my enjoyment of the good ones, so why should Watchmen be any different?
