The one problem I have with the final cut is the changes it makes to the Tyrell-Roy scene particularly what he says to Tyrell and later J F.
In the earlier versions of the scene he is fired up, barely repressing his rage until the final resolution where it explodes.
In the final cut what he does to J F doesn’t fit what he is saying to him and the F-bomb is sorely missed.
I can see why it was done, to foreshadow the final scenes, but it mucked up a pivotal scene for me.
