If this was a movie about Gordon investigating Joker, it would have probably been better. No stupid batman plot. No lame love story. No forgettable Two face.
shareI think it was on youtube, some time ago, a guy made a montage of all the scenes where the Joker appeared and put them one right after the other in chronological order. It was pretty neat. It was something like 40-45 minutes. I ended up watching the whole thing!
Now I'm thinking, if someone made the same thing but also added the scenes with Gordon... we could have something very close to what you are suggesting and I'm sure it would be very watchable.
