Thanks.
I can't disagree with you here. Regan is among the most memorable scenes in All Star. I wished to see Jonathan Kent's death and the Superman dynasty as well. Superman meeting the unnamed Superman from future makes the ending better for me personally. So as to say Superman will return. They should have given it two movies. The best Batman story has two parts adapting four issues. Best Superman story has one part adapting twelve. It shows in the final film.
I understand the length of the source material. For me its the small things they missed which bother me more. Like the aforementioned Regan. Another bit is when Superman punches out Solaris, they changed his dialogue from, "You will live" to something equivalent to "I have run out of mercy". A small thing in overall picture but it felt odd to me. Superman as Clark Kent used freeze breath to save Luthor in prison. But the film added that the frozen attackers were killed by Parasite. In comics it was fun to see Superman trying to save Luthor in prison. But in the film that makes it look like Superman let people die to save Luthor and protect his identity, where he could have tried to change to Superman and situation could have been resolved in a better way. This mars an otherwise fun sequence.
Luthor dressed up his chimpanzee in Superman costume. I love that panel showing the pettiness and hatred of Luthor. This was removed. Overall its decent. From the films i have seen so far i have enjoyed it the most. I agree with the brilliant score. i watched the whole credits just to hear the theme. When it comes to themes Superman has some fantastic ones. But people seem to like only the Williams one.
