Re: The mob - make it more intimidating
If WB plots out a longer Batman series, say 7 films like Harry Potter, the Mob should get a stronger representation. They can use the Mob to transition the audience into more science fantasy villains like Freeze, Ivy, and Clayface while blending the Mob with more classic villains like Penguin, Black Mask, Riddler etc.
Also, consider that Bruce had been training with an elite group of ninjas for however long. Its not as if he was going against the mob with the sort of inexperience he had in Year One (comic).
"Never call him that!" Spittle sprayed from Theon's lips. "Ramsay Bolton, not Ramsay Snow, never Snow, never, you have to remember his name, or he will hurt you."
"He is welcome to try. Whatever name he goes by."
