The World Has Been Avenged. When Will We See Justice?

First off, I’m not interested in writing a review for Marvel’s The Avengers.  Mainly because the internet is already flooded with various reviews and articles on how The Avengers beat the bad guys and obliterated box office records.  It’s obvious that the world loves The Avengers (myself included) except for apparently 7% of the critics out there according to Rotten Tomatoes.  What I am interested in writing about is how DC and Warner Bros. absolutely NEED to follow Marvel’s lead (no matter how much it may pain them) and create a series of their own super hero movies that lead to a Justice League film.
