I did an agonisingly long review of TKJ in my journal just the other day, prompted by picking it up and remembering how deeply it touched me as a young Joker fan many years ago.

I have yet to do a thorough comparison, but in the colouring - no, they can't be compared, although I do think the recolouring is better. If that even makes sense. I'd be interested in your thorough comparison as my reading copy of TKJ has gone AWOL!

The original colouring is bad-dream-esque - surreal - the new colouring is practically spartan. It's beautiful, delicate, stark and evocative. I still have a great deal of attachment to the original colouring but given how markedly different they are I don't blame Bolland for being disappointed with it as the original colourist and Bolland clearly had very different tones they wanted to convey. I especially loved the flashback scenes. I wish he'd kept Joker's purple eyes though. heh.

I noticed one particular edit to the Joker's mouth in the final few panels, where previously it had been turned down it was now almost smiling. I thought it was an interesting adjustment to make and tied it into some of my theories on what's going on in that end scene there.
