Re: How much did Ledgers death change the ending of DK?
I agree. The idea of Joker doing it is just a cool fanboy moment, but it doesn't make much sense in context. Also, what happens once Joker vanishes? That's too obvious of a setup for another movie where Blake goes at him. Bruce wouldn't retire knowing that Joker is back on the streets either.
Another reason why us fanboys shouldn't write the script.
"Guys, what would be your reaction if Alfred was Batgirl in this movie? You go watch the movie, everything cool, halfway through, Alfred becomes Batgirl."
