Dc has an issue when it comes to adapting properties. They can only seem to Adapt Superman and Batman, as heroes. Then instead of bringing on another hero they give us a Lame Jonah Hex film, or a lame minor character film. Then there is the Lame green lantern film. Here is what and when they need to do there Shared Universe films.
Ok, to get Marvel, they need at least three movies per year. Here is a time line and wht i think should happen.
The Man of Steel (2013)- Exactly what you think would happen in this film. And Maybe have a Oliver Queen cameo.
The Flash (2013)- Ok, make him witty and sarcastic. Make him the DCMU's Iron Man. Why? Audinaces like to laugh. Iron Man did so well because of its Humor, and loveable characters. Make him fight Captain Cold. And set up other Rogues. Have Cold freeze over and ocean or something and you could introduce Arthur Curry, as perhaps an activist for the ocean and keeping it clean and well.
Wonder Woman (2013)- Give Diana the Royal Treatment. Give he the Thor treatment. She will be the fantasy element of the movie. A strange woamn in a strange world. (No Cameo here, maybe just few easter eggs like A slew of Newspapers reporting on this new Hero, and one of them is a Daily Planet Article written by Clark Kent.)
Batman Reboot (2014) - I know a little too close, but to get to a justice league to need to establish this is not the batman from Dark Knight and Dark Knight rises and Begins. Skip the Origin all together, Batman has been fighting crime in Gotham for 5 years. Make the villain Someone we havent seen on screen yet. John Jones in his human form should make an appearance as a Detective working with Gotham PD and GOrdon, one of the few people Batman and Gordon Trust. Maybe reveal he is an alien during the final battle.
Green Lantern Sequel/Reboot (2014) Give this the Incredible Hulk treatment. Give the origin in the opening credits get it out of the way and get right on with the story. Set it entirely on Oa,and have Sinestro as the villain. After the struggle of the film and its villain beaten have Hal return to earth because he needs rest.
Aquaman (2014) - Use the Environmentalist aspect to an extent not making it Avatar or anything, but make it a small thing about Curry's character, use Black manta as the Villain, Give Curry the Hard Water powers and bam, great flick
By 2015 there should be at least one sequel, and it needs to be The Flash.
The Fastest Man Alive (2015) - Make Barry Suffer, give him a viallian that will test him mentally and physically, maybe professor zoom, or something, then Introduce Wally West, and set up the Justice League Plot.
Justice League (2015) Just in time to compete with Avengers 2, that would be a fight to watch... So yea, what do you think?
