Yeah I haven't seen the new version but I know the plot differs.
You know how in the original the prisoner's bus pulled over because one of them was sick, the police station was closing that night & you had the little girl being killed, the father's actions & then the cult's siege?
Well, in the new movie, there is none of that.
There is a gangster locked up in the station & there is somekind of storm & flood leaving the police station isolated (cliche or what). Anyways, a mob wants to kill the gangster & the cops have got to protect him.
From what I've heard & read it's meant to be quite good.
That said, the cult aspect of the original made it so dark & eerie, I doubt this one will fulfill this area but may make up for it in areas like special effects etc.
