I just saw the clips...they are not bad, but nothing to write to mom either.
Of course they are just seconds or minutes long, so, it not even cross my mind to say that it means that the movie sucks (which the clips don´t, so, i would never say that).
Two thing that caught my eyes when seeing them...the shirt rip and "and he doesn´t lie".
The shirt rip, might be classic Superman, but damn, he guy is running in a busy street, with a bunch cars in the streets...at least Reeve had the decency to get into a phone booth or a rotating door.
And about when Lois is explaning Superman´s powers to Richard....(which is weird, because would Richard know what they are, it makes Lois be extremely excited with his return that she just can´t shut up), the all "and he doesn´t lie!".
God damn it, i hate that!

I always hated the all "he doesn´t lie" crap.
It makes it look like it´s a power that he has...he doesn´t lie because he chooses not to, not because he can´t.
And then there is the clip "I Thought I Would Never See You Again" , which is, IMO, the worst of the bunch.
First of all (and this may be better in the movie, when we see the all scene), it doesn´t look all that dramatic, when it should be.
And the clip goes like this...
WTF?
I would have made a better dialogue than that, and more Superman like.
