I thought the trailer was surprisingly good, although it greatly pains me to say it.
The problem is they've strayed too far from the source material to be what they perceive to conform to popular culture. The change to how they get their powers is fine enough but the whole teen casting is played out to shit. There's a whole bunch of recent movies with younger casts that have failed big time, the actors in this do appear to be of at least 1/2 decent quality but it all boils down to wether or not the storyline and script are up to scratch and Fox's history sucks cock in this regard.
