Questions about Fantastic 4 trailer

[mainman]

I saw the trailer, and it was cool.

Silver Surfer (and Venom and Carnage) is my favourite character 'Marvel' has to offer. And I am not much of a DC fan, so...

Anyway, Silver Surfer looked cool man.

But in the trailer, it showed as if Silver Surfer 'eats' the world.
In the trailer it showed, wherever he goes, a part of the earth gets eaten.

All Silver Surfer should do, is search for worlds, and then call his master.

I would be really be disappointed if the movie shows the Silver Surfer as the devourerer of worlds. Silver Surfer is a hero (sort of), and should stay a hero.

Because I also want to see how Galactus would look in a movie (the dude should give your subwoofer a major workout).
