It's script is fine. People nitpick, people find complaints when they should just watch the film. I don't understand what's superfluous about it. We know Joker wants Gotham to swallow itself whole, fuck itself up. Piling on the misery only strengthens his position at the top of the food chain, all the gangsters don't sit around and think his plans are getting tiring and repetitive.
- Joker robs a bank and kills his crew and a mafioso. We discover that the Joker is insane, has a flair for the theatrical, is a pathological liar, and thrives on chaos.
- Joker interrupts a mob meeting and suggests murdering Batman. We discover that the Joker is insane, has a flair for the theatrical, is a pathological liar, and thrives on chaos. Again.
- Joker kills a Batman wannabe and hangs him from the mayor's office (and, for maximum combo points, manages to have him land perfectly in front of the mayor's window when he happens to be staring out of it). We discover that the Joker is insane, has a flair for the theatrical, is a pathological liar, and thrives on chaos. Uh huh.
- Joker puts bombs on Rachel and Harvey and gives Batman the addresses of where they are, but in reverse order. Batman goes for Rachel and ends up getting Harvey. Rachel dies. We discover that the Joker is insane, has a flair for the theatrical, is a pathological liar, and thrives on chaos. You don't say?
- Joker blows up a hospital and manipulates Dent. We discover that the Joker is insane, has a flair for the theatrical, is a pathological liar, and thrives on chaos. Yeah, I get it.
-etc.
Did we really need yet another scene to show all this about the Joker? At least the Rachel/Harvey scenes and the hospital scene were nicely conceived and executed.
With each successive plot he pulls off the movie becomes less and less believable (insert "believability? in a move about a man dressed as a bat?" comment here). There is suspension of disbelief, and then there is ignorance of it. Every single one of his plans hangs on so many little things he can't possibly control going perfectly right, and somehow they always do (aside from the ferry). We are told he is a "dog chasing cars" when in fact he has to be an intellectual giant with a horse shoe the size of the planet Krypton shoved up his ass in order to mastermind the shit he does in this movie.
