1. It's Now or Never 
I don't know about the rest of you, but I'm honestly tired of hearing about whether Justice League is going to be made or not. It's exciting the first time around, but the first time around (at least, in my experience) was a couple years ago. If anyone needs a reminded on how that turned out, ask George Miller. Every time a DC movie fails, the Justice League film is put into question. Every time Justice League is pushed back, it makes it look more and more like DC needs to give up the ghost and shelve the dream. Yet, with Marvel's Avengers success, the world is taunting DC to continue to try and make good on their promise, as the world has proven that it's ready for such a thing to happen. Failure to launch the DC Cinematic Universe into a cohesive, continuous franchise is going to cripple this brand's chances at cinematic success, relegating them to only Television, Animation and Comic Books. Film-making is the Comic Industry's "Fourth Estate", and it's rapidly becoming an essential one. The time for a Justice League movie is now, otherwise DC better just abandon all hope for ever making it. Marvel's already teed up the volley for you, and you've got enough time before Avengers 2 to try and make a competitive, art house blockbuster. You have the artistic clout, you have the resources, and you have the skills. But most importantly, you better lock Bale and Nolan into frame (or at the very least Nolan, with the option of a Bale cameo) if you even think of creating a Justice League universe. You don't need to reboot Batman. I've told you this before, and I'm sticking to it. Reverse the hasty reboot trend, and take back the multiplex! Otherwise, I hope you're ready to watch Marvel walk all up and down your face with their awesomeness for the next decade or so.
