Also, I just checked out a comic book from my local library, Superman comic, and guess what, it did not end on a high note. True, it was Vol. 1 of "Camelot Falls", and so I guess I should have checked out the other volumes, but I didn't, so I was left with an ambiguous not.
On the other hand, MOS ends on a very positive note. We move beyond the death of Zod.
Good call bro. I just read Superman Brainiac, by Geoff Johns, it ends with Clark sitting on the floor of the barn, head in his hands, mourning the loss of Pa Kent.
Another Johns masterpiece is "Last Son" which also doesn't end on a happy note at all.
But the thing is, these endings work, because while Superman always wins in the end, victory has its price.
I liked the MOS ending too, because it did have a positive note - I though the people who said they didn't feel hopeful afterwards must have seen a different film.
When Lois says "Welcome to the Planet" what she really means is, "welcome to the human race." this is Clark Kent stepping out of the shadows, true he's got a dual identity, but before he was trying to hide any trace of his existence from humanity.
Hopefully, subsequent films will show that people in Smallville all obviously know that Clark Kent is Superman, and Perry and Lombard will work out pretty quickly(as they've seen Superman in close proximity).
Anyway, blah blah blah, you feel good, because at last they guy's kind of found himself, which is what the majority of the film was about.
I reckon a sad ending in a Superman film would only work if there was an impending sequel (kind of like we all knew at the end of Empire strikes back that Return of the Jedi was coming, that would restore the good-evil balance and put good back on top). The ending of Superman returns was somewhere in the middle, which is why it didn't work for me.
Despite what people say, I believe that film and comics are different enough so that some things that work amazingly in comics have to be treated differently onscreen (hey, it worked for Lord of the Rings !).
Peace.
