To tell you the truth, I re-watched Superman: The Movie last week for the first time in a while, just because I was craving for another Superman fix until my next viewing of MOS. Maybe it was because it's been a while since I've watched it, but I just appreciated it so much. The Krypton scenes are stately and intriguing. Brando's performance as Jor-El gave the character gravitas, particularly if you were watching this in 1978. And the Smallville sequences are amazing. Every frame is beautiful - Norman Rockwell all the way.
That said, it might be significant that I lost interest and turned off the movie after the initial montage of Superman saving people. It's not because I don't like the whole movie, because I do. But it was like after seeing Christopher Reeve as Superman save a bunch of people, that was enough for the night. I think it's because all the scenes with Lex/Otis/Miss Tessmacher are just a completely different tone. Whenever I see those characters onscreen, the movie instantly seems to revert to the tone of the '60s Batman series.
Anyway, the point is that Donner did the Silver Age Superman as well as anyone could have done - and that's great, and his contributions will always be appreciated. But at the same time, I'm sick of watching the Donner version over and over and having everybody act like that is the only viable interpretation of the character.
What I loved about MOS above all else was its audacity to do something different with Superman. That's absolutely what the character needed, and I don't give a damn if critics want to live in the past and act like anything that doesn't slavishly imitate Donner is a mistake. **** them. I love MOS precisely because it takes risks and tries new things.
