I hate that I have to praise it just to say its name, but from the looks of the trailer, A Great New Wonderful is almost definitely the best 9/11-related movie coming out. That's probably because it takes place a year after the event and doesn't seem to mention it much. In fact, I'm not sure the trailer I watched was even about 9/11, or even the right trailer. It seems like there were an awful lot of talking cars.
For those still sensitive to the subject, understand that the title A Great New Wonderful is not claiming 9/11 was great or wonderful. It's just implying it.
