You know what's the main problem with every single Batman movie adaptation ever?
Batman is never badass enough, because in order to create a faithful adaptation of the comic it would have to be Batman- The Movie starring Batman.
What's worse is we're constantly stuck with Batman reboots, where we get to watch Bruce begin his campaign against supervillainy all over again, which has been done to death.
But if you really want to see Batman become the god among superheroes he was meant to be you've gotta dig into the vaults and check out all the alternate versions of Batman found exclusively in the comics.
There you'll see Batman as a member of the Green Lantern Corps., a Victorian Batman hunting down Jack the Ripper, a few different versions of Vampire Batman, and the time Batman sat atop the Mobius Chair and actually became a god.
