I have to praise how good the animation was. The voices seem to be pretty spot-on too! I was expecting Bane to make fun of how Batman's voice wasn't that clear either. I just did not like the rest of it. It came off as too short, and it was basically just one joke that never really went anywhere. It falls on Bane and he dies.
I don't see how that specifically mocks the movie or anything else. You at least did your research for getting the theme right. Why are the DKR parodies only coming now? They didn't when the movie first came out. I guess it just takes time to make flash.
