Regarding the tinting - Firstly I noticed they did it at other points as well, Gold flashbacks when the Comedian is talking to Moloch. But then I had another idea as well, What about only having the flashbacks RED at points of impact?

Like as the Comedian is punched in the face. That would probably be right before it cuts back to the present. It could be a good idea and a bit of a "best of both worlds" approach. I might do some mockups after work to show you clearly what I mean...I had an idea for a yellow on black title as well that might work. Just don't have time right now. gotta get to work.

EDIT: okay I'll try to illustrate my point here quickly - Here you can see that the flashbacks of the fight are in red - If that's too overwhelming you could try something like this...

Comic shot -

Now you COULD cut from the cops talking about blake to a part of the fight - I chose these images at random!

Keep the cops talking as we see a part of the fight, here the Comedian is about to collide with his coffee table...

now at the point of impact [ table breaking] you coul quickly cut to a red tint - probably best with a smooth crossfade...and possibly even try a bright flash as it happens

keep the scene red for the duration of the shot - which wouldn't be too long, then cut cleanly back to the present.

I'm sure if it happens quick enough it could have a good amout of visual impact.
