Here's another big part of what will determine the success of the movie I feel. The tone of the movie (mainly in the sense of how dark and serious it is) could be like Nolan's Dark Knight trilogy or lighthearted and fun like the Avengers. Or somewhere in the middle or even more extreme than either of the two. Personally, I think it would be best suited somewhere in the middle. I was pretty disappointed to hear the mass rumors that Will Beall wrote the script to be closer to the Dark Knight's sense of seriousness (even though I'm pretty sure no one knows enough about it to be positive on this). The JLA, if anything, is more fantasy based than the Avengers with both the characters on the team and the stories they live through. To make the movie as adult appealing as Nolan's Batman could end up making it seem forced as well as not bringing in as much money (the Avengers viewing I went to had 3+ times as many kids as TDKR viewing I went to and I feel like overall the Avengers made more money partially due to more families going to see it together). On the other side of things, I would like to see the JL movie stay away from the amount of humor Avengers had in it. The jokes worked well especially for the ridiculousness of Iron Man and Thor's characters and their egos but for Justice League I feel like it'd be funnier if the jokes came more subtly. But plot will be king here since it's looking like there won't be much lead up character or storywise for this so they'll need to focus harder on setting up the setting than really making personalities sparkle the way Marvel's guys did. I really like how the tone of the story is presented in this fan trailer (more like a sneak preview). The story itself that the person made up could probably use some tweaking but I feel like this would work well stylistically. http://www.youtube.com/watch?v=jqPneLQAw_Q So what do you guys think? How dark and gritty should this thing be?
