Personally i don't mind that Joesph Gordon-Levitt..being Batman.I know a lot of you Comic Book Fans hate the idea but honestly i think it is a decent idea..as for the next next Batman Movie..well now JGL is going to be Batman.. I've got a couple ideas for it:
1. Have JGL where the Batman Beyond Costume
If JGL ends up being Batman..i think that the Batman Beyond Costume would work best
2.Have Barbara Gordon in the Film
One of the things i wasn't happy about was the lack of the Barbara Gordon. Personally i feel that she would be great as John's girlfriend in the movie and maybe have her become Batgirl in the 2nd or 3rd film.
3.Have Anarky be the main villain in the film
I know a lot of people will say..why not Riddler or Penguin? Well personally as much as i like both villains..i think the first film should be a lot more about the Hero than the villain but still Anarky would be a great choice for the main villain.
4.Have Jason Todd/Red Hood appear in the film
Personally i think he could be a great anti hero in the film.He wouldn't be the main villain but he still fights Batman.As for backstory..well i think he could be a former best friend of John who runs a gang.
5. Have returning characters from the Nolan Trilogy in the film
I don't expect Alfred in the film but i really think Lucius Fox and Commisoner Gordon should return for this film.
