What they should’ve done, in my opinion, is at least focus on the fallout of Arthur killing Murray. They were partially there with the courtroom scenes and plot line, but showing more of the breakdown in Gotham as the trial goes on would’ve been good. Just axe the whole Harley plot line. As the case goes on more unrest and rioting occurs until finally the guilty verdict is given causing Joker supporters to erupt and raid the courthouse, freeing Joker. Also spoiler here: >!have the ending stay very similar to the actual film where the explosion at the courthouse sets Joker free, but then ultimately gets caught again then killed by the Heath Ledger Joker in Arkham. It doesn’t make sense in the context of the actual film because there’s no setup for it but it could work in this alternative version if you give a build up to that eventual payout.!<

What do I know though
