this is not so much what I would add, but rather, something that I would change, and someone else that would be fired or demoted in the F/X department.
the shot of Superman landing in the fortress. The hard landing. Now I know I'm being nit picky, but of all the shots in the trailer, that is the one that stands out the most as just looking WRONG. In the shot, superman's legs bend, making him look all 'monkey' like. The conceptual idea for the shot is worthwhile, but the way they make it work on screen just doesn't look right.
Superman's legs wouldn't bend like that. The ground would move out of his way for his landing, ei. he would leave a crator, not cracks in the ice/crystal. I think the Cartoon handled shots like this much better, and I hope it's one of the things they revise in the final weeks.
I mean it just doesn't look right, from the unatural movement, to the strange hunched position he is in upon landing.
other than that, the only thing I'd change in the trailer is that I would have tired to intergrate some of the teaser trailer into the full trailer. The teaser had this deep feeling, especially with the monologue, and the krypton theme playing. But this seemed to be lost in the full trailer I think an integration of the two previews would have worked better. Add the depth of the teaser, with the fun and frolic of the full preview, and I think it would have worked out better.
And lastly, I'd just like to say, that there have been a lot of fan trailers that worked better than this preview, which feels like it was pieced together, rather than being one coherent unit, like the teaser was.
PS. Can't wait to see what the fan trailer boys can do with all this new material at their disposal. Hope that some new fan trailers come out soon, because I'd like to see someone take the material that we have now, and reorganize it into a better trailer
