Quoted from PeterG:
I think almost all agree that there is little to tweak on the original sounds and call outs. It is my only pin with standard sound.
I agree completely, the callouts from J.K. Simmons are some of the best in any game ever and the custom music is spot-on for pinball. Since all the other clips are from the movie and not voice actors I can't think of much, if anything, I'd want changed.
