No, you never do leave the diner. But it is quite a ride. What do you really want? And what would you be willing to do for it?
"I hear they serve a great pastrami sandwich here." All you have to say. Of course you have to know what it is you want.
"24" fans will enjoy seeing Xander and another actor. And it gave me food for thought. It is the sort of movie, that if you like this sort of thing (i do), it is very interesting and well done. Nothing fancy, just human beings, some of whom are in tough spots, and some of whom are willing to do more than they ever contemplated to solve their "problem." No blood, no gore, no tricks, ... just the diner and the man who grants what you want for a price that you decide you are willing to pay.
