M. Night Shyamalan might not engender a lot of faith in his directorial abilities, especially since at this point he can't even be bothered to hide the plot twist in the movie but chose to blow the big reveal at the end of the trailer.
However, the screenplay is co-written by Gary Whitta, who worked on Book of Eli and wrote an episode of the critically acclaimed Walking Dead game.
So whether this will turn out to be a "You blew it up! Ah, damn you! God damn you all to hell!" or some parallel universe or an elaborate virtual reality gone on the fritz or some fourth thing remains to be seen.
