It looks neat but I'm confused as to why Batman says he's back in the Middle Ages.
I always thought Middle Ages referred to a large point in time where authority preferred Might Makes Right over Intelligence. This isn't to say that Japan didn't have a Middle Age. Rather it is to say its confusing to see Batman go back in to protect what should be Middle Age Criminals from other Criminals.

On the other hand Bruce Wayne is a Billionaire who secretly beats up poor people who have turned to the life of being henchmen.
