Will there be a hero? One with flaws (ok, an absolute idiot) that need to be pointed out incessantly by some skank who's so tough she can kick everyone's ass but his? You know, as rough as she's supposed to be sexy but with all of the physical charm of a can opener? Can I count on there being a jaunty sidekick? Without a jaunty sidekick who wears a grandpa hat and overly large sunglasses at the end, the idiot and the skank might not discover that they're made for each other after all.
And what about the tech? Can I count on it to not only exceed science fiction but be based on a hodgepodge of buzzwords that not only don't go together but flatly contradict physical law? Can we get someone to play the scientist and explain that, who's expert in portraying how clueless he is about people? Preferably one devoid of common sense. Finally, is there any chance whatsoever that we can get some hipster nerd who can hack NSA mainframes with his toothbrush to provide the breakthrough scene where he co-stars with a really loud keyboard and several large monitors and in a surprise upset gets the idiot and the skank back on track with his kung fu virus skills?
You know, something like that - something original.
PS - Please see to it that none of them get near a bottle of shampoo and the only ones without stubble are the nerd and some of the chicks. Because God knows that you can't own a comb or bathe and be qualified for anything during an apocalypse.
EDIT - I forgot about the fx. Make it really sensational so people can say how realistic it was when physical laws got thrown out the window.
And don't worry about the dialog a lot, that's why they invented camera angles and idiots and skanks that wouldn't know cool if it walked up and slapped them.
