what could he have?It'll be a case of wait and see for myself. I can't say I saw anything that was overly impressive in the trailer, don't now how to describe it but it's almost as if it's exactly what I was expecting I'd get as a teaser for this film, especially after seeing the recent character one sheets. I know the guy is good with the visuals and all but has always comes up well short with character and story, this is probably the film which tips me one way or the other for Sydner, until now I've been on the fence with him because he's mostly done adapted material, to me this is the moment he shows whether he's got what it takes or whether he's just a better version of Michael Bay (although I'd still watch his stuff over Bay's any day).
does he really need to have more substance?
because IMO directors who have more substance dont do movies like Sucker Punch. and i f.... love how this movie looks. i am happy that Snyder did this.
It's a shame that people feel the need to hammer negativity like there is a damn quota that needs to be filled...
Have we all forgotten that this is the same director who made zombies AWESOME again with his Dawn of the Dead remake? That movie PROVES he's a good director with plenty of substance!
Inception trailer was also all visual no substance but I guess if it was Nolan and not Synder who made this movie it would have been different.

you're only as good as your last movie. for instance spielberg and jackson have lost the plot (pun intended).
