DC is a gritty multiverse. You would think that a title called "Extreme Justice" would have been true to its name.
Not the case.
Check out the following link, and see for yourself: http://www.comicvine.com/extreme-justice/4050-5505/
Personally, I think that Extreme Justice fits better in to the current trend for books.
I think that if the book had a different cast, it would have been more popular.
Here are my recommendations for the perfect EXTREME JUSTICE Team:
1. Captain Atom ( the more recent version) https://en.wikipedia.org/wiki/Captain_Atom
2. A Red Lantern (either Guy Gardner, Rankorr-Jack Moore, or Bleez )https://en.wikipedia.org/wiki/Red_Lantern_Corps
3. Crimson Avenger ( the one Geoff Johns created for his run on JSA) https://en.wikipedia.org/wiki/Crimson_Avenger
4. The Spectre. https://en.wikipedia.org/wiki/Spectre_(comics)
5. Trantuala. http://dc.wikia.com/wiki/Catalina_Flores_(New_Earth)
6. Lobo. http://dc.wikia.com/wiki/Lobo
7. Nemesis. The Geoff Johns version of this character would be great. http://dc.wikia.com/wiki/File:Nemesis_Soseh_Mykros_0001.jpg
8. SPYDER: http://dc.wikia.com/wiki/Thomas_Ludlow_Dalt_(New_Earth)
Each of these Heroes has been extreme and would fit into the new team.
This team would also be able to handle some of DC's Nastiest villains. I guarantee that in the right hands, this team would have great stories.
Just a thought.
To Be Continued....
Go forth and do well.
