agreed, that's a very good point.
What SR lacked, for me, was a real sense that Supes felt/realized that he really messed up. Yah, I know that he said he was sorry to Lois on the rooftop....and others here say that there were subtle indications.
Perhaps that is true. But, for me, I just didn't FEEL that Supes really acknowledged/took responsibility for the entire mess he created. It's like he says...."I'm sorry" and that's the end of it.....he goes off doing his Superman business as usual.
I contrast that with Superman 2 ( Donner's Cut ) and Spider-man 3:
Superman 2 ( Donner's Cut ):
There's a scene where the powerless Supes is talking with Jor-El and Supes ADMITS that he made a mistake, that he let everyone down by his decision. This is also the scene where Jor-El gives the "Son becomes the Father...Father becomes the Son" speech and gives up his "essence" to restore Superman's power.
You can tell and FEEL from this scene that Superman/Clark really feels remorse for the mistake he made.
Spider-man 3:
In Spidey 3, Peter turns into a jerk as he is consumed by arrogance, vengeance, and the symbiote suit. Peter ends up hurting the ppl he loves the most ( namely MJ ) and this comes to a culmination in the bar scene.
After Peter shows off his dancing skills ( to impress Gwen and spite MJ ), Peter and MJ get into an argument and Peter shoves MJ to the ground. This act snaps Peter out of his state of mind.....and the look on his face clearly shows that he realizes that he is turning into a monster....that he has to get rid of the symbiote suit and its evil influence.
Also, at the end, when Sandman confronts Peter to ask for forgiveness and tell his side of the story.......Peter forgives him while also admitting that he has made mistakes in his life too........that he has hurt ppl too.......(Peter also admits that he has hurt MJ to his Aunt).
Both of these movies show that our beloved heros are not perfect......that they are capable of making mistakes.......but.....more importantly.....that they ACKNOWLEDGE AND LEARN FROM THEIR MISTAKES!!!
And, for me, that's what SR really lacked. Perhaps it was due to poor editing....but the movie never really took the time to allow Supes to ponder and reflect on the mistakes that he made. It's like he returned and BOOM we're shuffled from scene to the next. There really was never a scene where we saw and FELT Supes thinking to himself..."Y'know what Kal-el!! You really SCREWED THINGS UP!!!! How are you going to FIX THIS!"
