I said this in another thread but I think I may need to expand on it. Batman is not Iron Man. Batman is not Captain America. It is impossible to capture the essence and the mythos of Batman and limit it to just one film... just for the sake of tying him into some kind of DC shared universe. That is selling both DC and the character far too short. The Captain America movie told you pretty much everything you needed to know about Captain America. We got the origin and we got the Red Skull. All it took was one Cap movie for the general audience to really grasp the essence of the character. But Batman is not Captain America. He's far more a cultural icon. His mythology is richer and it is far more complex. Gotham City and it's makeup lend itself to more than just one movie. This is Batman, and unfortunately his being expands beyond just one definitive tale. In fact, there is no definitive tale that can be covered in just one movie. To have just one Batman movie... and then feature him in some DC crossover like Justice League or World's Finest would be a disaster in my opinion. Batman belongs in Gotham, not in outer space fighting alongside aliens and gods. If WB wants to take Batman there? Fine. But only after he has a firmly established, developed mythology in Gotham. I say they need AT LEAST two solo Bat-films before they even consider putting him in something else, maybe even three. Just one man's opinion of course. I know, I know... wishful thinking. I'm sure they want a JLA movie sooner than later and I doubt they have the patience or the foresight to see it through like that. A solo movie for guys like Flash and Aquaman would work just fine. All they need is an introduction and a stand-alone adventure to make themselves familiar with the general audience. But Batman needs more than that. He and Superman are bigger than the rest. One movie is not enough.
