A very, very fine fanedit - well done Jorge, this is a marvellous piece of work.
I won't go into all the details that others have already listed, but I'll add a few constructive criticisms of my own if I may, as follows:
a) I really didn't think that the last scene worked between Gordon and Batman - for one thing, being lifted from Batman Begins, the sound and visual textures were a bit different and didn't meld so well compared to the lifts of Wayne as a child. For another, I thought that it spoiled the narrative flow. I would have put back in the scene from the theatrical release, ie Batman driving away on the Batpod.
b) A few brief bits of dialogue that I would have cut near the end with the chase, leading to the truck flipping -
(i) at one point a police driver says "We'll be like turkeys on thanksgiving"
(ii) Another guy (same driver?) says "load and load"
(iii) general remarks from cops in that whole sequence. I'd have cut them all.
c) Final point - near the end, the Joker pushes the driver from the truck and says "Excuse me, my turn to drive" - I thought that the edit after that line was a bit jarring.
Sorry to criticise, overall it was a first rate edit. These are just the things the niggled me.
Fantastic work overall though. Well done Jorge.
